Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for determining bonding strength of ceramic coatings Ingestion-build-58320 What is BS EN 61158-4-211 Scope This document specifies the testing method for the determination of the bonding strength of ceramic coatings at ambient temperature by the compression tests on the cross joined test pieces. Methods for test piece preparation, test mode and rate, data collection and reporting procedures are addressed. This document applies primarily to any ceramic coatings, thick or thin, bonded onto substrates of various materials. The test method described
