Fine ceramics (advanced ceramics, advanced technical ceramics) - Rockwell indentation test for evaluation of adhesion of ceramic coatings (ISO 26443:2023)
08-11-2023
This document specifies a method for the qualitative evaluation of the adhesion of ceramic coatings up to 20μm thick by indentation with a Rockwell diamond indenter. The formation of cracks after indentation can also reveal cohesive failure. The indentations are made with a Rockwell hardness test instrument.The method described in this document can also be suitable for evaluating the adhesion of metallic coatings.The test is not suitable for elastic coatings on hard substrates.
