Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for determining density of ceramic coatings subscription-only Laboratory and practical performance tests1 Scope This document specifies a testing method for determining the density of thick ceramic coatings at ambient temperature using the Archimedes method. Methods for test piece preparation, test modes, data collection and density calculation are addressed. This document applies to ceramic coatings with a thickness > 0,1 mm including thermal barrier coatings, wear resistance coatings and other thick coatings on metal or ceramic substrates.
