WebThe scratch test is an established method in material testing. Done in a laboratory setting, it simulates the kinds of stresses that a coating will undergo in everyday use. According to …
WebThe scratch test is a quantitative test with high repeatability. The critical load depends on the mechanical strength (adhesion, cohesion) of a combined coating-substrate system but also on several other parameters. Some of them are directly related to the test itself, while others are related to the coating-substrate system.
