Mechanical testing

The mechanical testing of coatings on a substrate is an essential step to ensure the quality and performance of the applied surface treatment. This test aims to evaluate the mechanical properties of the coating in terms of hardness, adhesion, scratch resistance and other relevant parameters.

An important aspect of the mechanical test is the hardness of the coating. Various test methods such as the Vickers or Rockwell hardness test are used to measure the coating's resistance to external influences. Sufficient hardness is crucial to ensure that the coating meets the specific requirements of the application and is protected against abrasion, scratches or other mechanical stresses.

The adhesion strength between the coating and the substrate is another critical parameter that can be evaluated using various test methods such as the scratch test or the pull-off test. Good adhesion ensures that the coating is firmly bonded to the substrate and does not peel or flake off prematurely.

Scratch resistance is another indicator of the performance of a coating. Special testing equipment is used to test the coating's resistance to scratches and abrasion. A robust coating should be able to withstand everyday wear and tear without losing its integrity.

Overall, the mechanical testing of coatings on the substrate serves to ensure that the applied surface treatments meet the necessary mechanical requirements. This ensures not only long-lasting performance, but also high quality and reliability of the treated surface in various applications.
