The Rockwell test is a standard method to determine the coating adhesion of carbon-based films and other hard coatings (PVD, CVD).
Following this procedure, a standard Rockwell C hardness test is performed on a coated component. The deterioration at the margin of the Rockwell indentation is assessed qualitatively and assigned to an adherence class (1 to 6) on the base of a visual impression (DIN 4856).
