scratch testing

Scratch testing, using nano loads, has become widely used for the study of adhesion strength and marring resistance of thin films and coatings. This same test can also be used to study fracture behavior on brittle substrates similar to a marring resistance test approach. This can provide an in-depth observation of failure on delicate substrate materials at precisely controlled and recorded loads.

One of the major concerns for composite material is it’s durability in final form. The size of particles that form the strengthening additive can drastically affect the overall final performance of the composite material. By using the nano scratch testing method the failure of composite material can be compared to identify the most durable formula.
