FISCHER SOLUTIONS FOR THE AEROSPACE INDUSTRY

Providing greater effectiveness, accuracy and savings in quality control

The Aerospace industry and its challenges

The aerospace industry is constantly innovating, looking for high technology challenges to further improve the quality of aircraft. It can be difficult to find suppliers and partners who are aligned with these technology challenges. Helmut Fischer, as a global partner of the major aerospace industries and their suppliers, provides the best technologies for measuring the thickness of electrodeposited coatings of Cd, ZnNi, Cr, Ni, Cu and NiP, among others, as well as paint coatings for space, by immersion or electrostatic painting, also known as KTL. In addition to controlling the layer thickness quality for various components, Fischer equipment also makes it possible to check the element composition of alloys and the chemical composition of galvanic baths among other challenges within the electroplating sector

In the aerospace industry it is also essential to comply with strict quality standards such as ISO 17025 / AS/EN 9100; AS/EN9110; AS/EN9120 and AS9003, and this is why, in addition to providing equipment, Fischer also provides calibration standards with several levels of international certification.

To meet the demands of the aerospace industry and its suppliers, Helmut Fischer offers a full range of high-precision products.

FMP® SERIES

The FMP Series of layer thickness gauges together with our high-precision probes allow for

non-destructive and highly accurate measurements of paint coatings and lacquers. Whether it’s for quality control in a manufacturing process, random sample inspection or complete batches, these portable, easy-to-use instruments will meet your needs. With more than 70 different types of probes, even the most difficult jobs, such as measuring on rough surfaces, in holes and tubes, on concave or convex surfaces and many other challenges, can be overcome with one of our special probes.

INSPECTION PLAN FOR FMP® 100 AND 150

The DataCenter IP (Inspection Plan) software was developed to optimise the management of results obtained in the measurements of components, providing a simple inspection plan for statistical control of coating thickness by systematically showing the measurements at the same points regardless of who is performing the inspection.

The DataCenter IP (Inspection Plan) allows you to use simplified drawings of the exact point of measurement on the surface of the sample.

All versions of the DataCenter software include a powerful tool for quality control – the Factory Diagnostic Diagram (FDD) developed and patented by Fischer. The FDD allows visual processing of measurement data or characteristic data derived from measurement groups.

The measurement data collected during inspections can be easily and quickly transferred to FISCHER DataCenter using USB- ports, Bluetooth and Wi-Fi, speeding up the reporting process and avoiding errors that could result from transferring such data by hand.

MAIN SPECIAL PROBES FOR FMP® SERIES

V7FKB4 Probe

This probe is suitable for measuring paint or metal coatings between 0μm and 2000μm because of its high precision and repeatability when measuring coatings on rough substrates of steel or iron base material (NC / Fe and NF / Fe).

FGAB1.3 Probe

This probe is ideal for measuring paint or metal coatings on steel or iron base material (NC / Fe and NF / Fe) with different types of geometry, or small measurement areas and is highly accurate throughout the entire measuring range of up to 2000μm.

FTD3.3 Probe

This probe is suitable for measuring the thickness of thin coatings of paint, lacquers and anodization on non-ferrous substrates such as aluminium, copper or brass (NC / NF). It has excellent levels of accuracy due to its unique technology for curvature compensation throughout the range, from 0μm to 1200μm.

FTA3.3-5.6 Probe – High Precision for anodization on rough substrates

This probe is suitable for measuring the thickness of thin coatings of paint, lacquers, and anodization on non-ferrous substrates such as aluminium, copper or brass (NC / NF). Due to the large radius of the probe tip, it has a greater contact area when measuring on uneven and rough surfaces.

FGABI1.3-150 Probe / FAI3.3-150 – Rod Probe

This probe is suitable for measuring paint or metal coatings in hard-to-reach locations such as pipes, holes, and grooves on ferrous or non-ferrous substrates (NC/Fe and NF/Fe), depending on the model of the probe.

FD13H Probe – Automatic substrate recognition

This probe is ideal for measuring the thickness of paint or metal coatings on ferrous or non-ferrous substrates due to its automatic substrate recognition technology.

FISCHERSCOPE® MMS® PC2

With its modern design, the MMS® PC2 can be easily used in your laboratory or on the production line to connect up to 8 different probe models among the more than 70 available, ready and calibrated for simultaneous use.

The Automation version of the MMS® PC2 already has the interface technology to be connected on the production line and controlled by a robot, with its results being automatically reported in an integrated way in your management system for quick decision-making for quality control.

MEASURING STAND FOR SECURING PROBES

For accurate measuring on small parts such as wires, pressed pieces, screws, or parts with complex geometries, it is essential to use the V12 stand for securing the probe in the correct position at the desired point of measurement, thereby preventing any interference from positioning or handling by the operator. If quality control is done by different operators, such as in shifts, the accuracy and repeatability of the measurements taken with the V12 stand can be easily verified when compared to manual measurements by different operators using the same probe.

SIGMASCOPE® SMP350

The SIGMASCOPE® SMP350 uses electrical conductivity to measure the properties of aluminium, copper, brass, and other non-ferrous materials, according to DIN EN 2004-1 and ASTM E 1004. With the SIGMAS-COPE® SMP350 we can correlate the hardness and resistance of materials subjected to heat treatment, as well as evidence of material fatigue. This type of evaluation can be carried out without damaging the sample, even when covered with non-conductive paints or coatings of up to 500μm thick.

The probes used are suitable for different measuring frequencies, ranging from 15kHz to 2MHz for a measuring range of 0.5 – 65 MS/m or 1 – 112% IACS. For automatic temperature compensation, an external sensor can be connected to the equipment.

CERTIFIED CALIBRATION STANDARD

For reliable measurements it is necessary to use calibration standards that meet the requirements of the quality management system.

FISCHER offers a wide range of certified standards according to the procedure accredited by DAkkS/ISO 17025.

The portfolio includes more than 300 calibration standards and covers a large number of applications for different materials, be they layer thickness, element composition or analysis of materials.

X-RAY FLUORESCENCE

Tailor-made for layer analysis or element composition, FISCHERSCOPE X-Rays can be used on a wide range of different electrodeposited materials, measuring the layer thickness on parts with different geometries. Because of its excellent accuracy and repeatability, it is easy to control its process via X-rays using calibrated and traceable methods in accordance with the most demanding standards in the aerospace industry.

For field inspections, where portability is normally required, the fully portable FISCHERSCOPE XAN® 500 can perform measurements of layer thickness and element composition in a few seconds.

Applications:

  • Determining the thickness of single or multiple layers, from nanometres to micrometres, in products with different geometries.
  • Analysing galvanic baths (liquids), measuring the chemical composition and contaminants for a better scaling of processes.
  • Complies with EN 61010, DIN ISO 3497 and ASTM B 568.
  • Measuring coating thickness of Cd/Fe; Cr/Ni/Base, ZnNi/Fe, Zn/Fe, Cr/Fe, Sn/Al, among others.
  • Determining the layer thickness on electronic components: Au/Ni/ Cu/Base, Au/Pd/NiP/Base, Cu/PCB, among others.
  • Measuring lead (Pb) or SnPb3 content, in PCB and electronic components.
  • Checking for heavy metals in accordance with the RoHS and WEEE directives.
  • Determining the element content of precious metals such as Au, Ag, Pt, Pd, Ru, Rh, among others.

X-RAY FLUORESCENCE - SOLUTION ANALYSIS (GALVANIC BATHS)

Companies that use a galvanic process need to monitor and control the formulation of their baths very closely. Controlling the composition of the bath can determine the quality of the layer of electrodeposited material applied. For example, metal coatings of ZnNi, SnPb, Cd, AuAgCu, Ni, among others, can be monitored both in their composition in the bath and in the thickness of the layer applied onto the part.

Using a measuring cell, the galvanic bath can be analysed and any metals in the solution identified immediately by analysing all of the elements simultaneously in just a few seconds, eliminating the need for sample preparation and/or use of reagents.

NANOHARDNESS

The quality of the coating, whether it is anticorrosive or decorative, is not only correlated to the thickness of the layer but also its element composition; the mechanical properties of such coatings are of paramount importance in quality control. The HM series of nanoindenters offer much more than only the traditional measurement of nanohardness. The instrumented indentation test does not depend on images or operators, and it shows several parameters such as Martens Hardness (MH), Vickers Hardness (VH), elasticity and plasticity module, among other mechanical properties. During the nanoindentation trial, these and several other properties can be ascertained for sizing the coating correctly, whether it is organic, such as varnish, paint or polymers, or metal such as zinc, zinc-nickel, chromium or even coatings of hard materials such as DLC, PVD and many others.

Another huge advantage of Fischer’s Nanoindentation technique is the transforming of inaccurate hardness tests on the market, such as the “pencil hardness test”, into a professional analysis with controlled forces on the mN scale, allowing for the analysis of ultra-thin coatings with excellent precision, in accordance with strict standards such as DIN EN ISO 14577-1 and ASTM E 2546.

Scratch Tester

Adhesion and cohesion of coatings on the substrate are other important properties to be controlled. The Automatic Scratch Tester system characterizes the adhesion force of the coatings on the substrate in an extremely precise way. It is also possible to replace rudimentary testing of adhesion, such as the pull-off and cross-cut test, where a force is applied manually without any control. With the Scratch Tester you can easily check the adhesion and cohesive resistance of layers with a thickness of ≥1μm by applying controlled forces on an mN scale and succeed in obtaining the critical forces according to the force applied. The response from the equipment will be the exact classification of the Critical Forces needed for the surface to start suffering damage, or even when it is completely removed, allowing such coatings to be scaled and applied exactly within the required specifications. This type of equipment is ideal for use in product development, but also for quality assurance or raw material control.

With an automated system for moving the measuring table, it can carry out a large quantity of measurements daily.

Common applications:

  • The grading of coatings of hard materials such as PVD, CVD.
  • The grading of coatings on components for engines, turbines, landing gear, fuselage, and others. Analysis of the adhesion of anodised or painted coatings.
  • Measurement of coatings on electronic components such as connectors, electronic circuit boards, among others.
