Fine ceramics (advanced ceramics, advanced technical ceramics) — Rockwell indentation test for evaluation of adhesion of ceramic coatings
|Publication Date:||15 June 2008|
|ICS Code (Advanced ceramics):||81.060.30|
This International Standard specifies a method for the qualitative evaluation of the adhesion of ceramic coatings up to 20 μm thick by indentation with a Rockwell diamond indenter. 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 coatings on hard substrates.
