Metallography

Coating thickness & porosity
 
Metallographic cross section with optical micrograph analysis to determine the:
 
  • Coating thickness according to ASTM F1854
  • Porosity according to ASTM E2109 
  • Mean Void Intercept Length - MVIL accorting to ASTM 1854
  • Tissue Interface Gradients - TIH according to ASTM 1854
These measurements require the use of high-precision control measurement technology and the necessary experience in handling the preparation of the measurement sample.
 
With the appropriate magnification, the clear and precise images provide all the necessary information for complete analysis of the coating.

Adhesion

Tensile and Shear test

Coating of test samples, preparation, performance and determination of:

  • Tensile test according to
    ASTM 1147 and ISO 13779-4
  • Shear test according to
    ASTM F 1044
  • Shear fatigue testing according to ASTM F 1160


Tensile force up to 50 kN

The tensile adhesion test is used to determine the adhesive tensile and shear strength of thermally sprayed coatings and substrate material (especially in medical technology) under tensile or shear load.
Using effective and flexible software, we perform tests according to existing standards and customer requirements and provide the associated test reports.
(We develop specific bonding fixtures to perform tests suitable to your test sample and specified test requirements).

Abriebtest
Taber_Abraser_Test

Abrasion

Taber tests

Coating of test plates, performance and determination of

  • Abrasion resistance (Taber Abraser) of metallic spray coatings according to Porosity according to ASTM F 1978

This test method qualifies the abrasion resistance of metallic coatings, produced by thermal spray processes on flat surfaces.

The specimens to be tested, placed on the turntable of the abrasion device, are subjected to the abrasion effect by two grinding wheels with fixed pressure.

Abrasion resistance is checked for all possible angles with respect to the specimen and measured with an accuracy of up to 0.0001g

Roughness

Roughness measurement
 
Performance and determination of:
 
  • Roughness measurement according to ISO 4287/4288 und ISO 3274
Measurement method for the individual measurement task.
Measurements of surfaces of grid blasted and coated test specimens or implants with fine diamond tip which can record the smallest roughness’s

Optical Scanner (GOM)

Coating thickness distribution
 
Contactless analysis of:
 
Layer thickness and distribution on components/implants.

A non-destructive method with high resolution for all layers.
3D analysis is particularly suitable for the three-dimensional measurement of objects and enables the conversion of a physical object into a digital file for analytical evaluation.

XRD

Röntgendiffraktion

X-ray diffraction

Performance and analysis of:

• Crystallinity of calcium phosphate spray powders and coatings according to ISO 13779

Powder Laboratory
