Some complementary scratch resistance characterization methods
Physics and Astronomy
In the characterization of mar/scratch resistance of coatings/materials with single-probe techniques, the probe usually scrapes the tested surface under a constant load or increasing load, followed by dimensional measurements of the scratch, identification of the critical force at which cracking/fracture occurs, or evaluation with optical instruments. Due to a variety of coatings/materials properties and various application requirements, the single-probe method may not provide pertinent characterization of coatings/materials in their applications in some cases. Three complementary test methods are presented in this article: i.e., a crack density measurement used for fragile thermoplastic olefin (TPO), a repeated scratching test, and a cross-scratching test used for glazing materials for automobile windows.
