Thermal spraying. Evaluation of adhesion/cohesion of thermal sprayed ceramic coatings by transverse scratch testing Ingestion-build-48348 Annex A A (informative) Rationale1 Scope This International Standard specifies a method for adhesion and cohesion evaluation of thermal sprayed ceramic coating substrate systems by means of a transverse scratch test. This International Standard is suitable for thermal sprayed ceramic coatings with thickness from 50 m to over 1 000 m. It is also suitable for testing ceramic coatings deposited by other spray coating processes, such as cold spray, as well as aerosol deposition.
