scope:
This International Standard specifies a method for the qualitative evaluation of the adhesion of ceramic coatingsN1) up to 20 μm thick by indentation with a Rockwell diamond indenterN1). The formation of cracks after indentation may also reveal cohesive failure. The indentations are made with a Rockwell hardness test instrument.
The method described in this International Standard may also be suitable for evaluating the adhesion of metallic coatings.
The test is not suitable for elastic coatingsN1) on hard substrates
