Metallic and other inorganic coatings — Vickers and Knoop microhardness tests ISO 4516:2002

Publication date:   Jun 20, 2002

Scope

ISO 4516 describes the application of the Vickers and Knoop micro-indentation tests for determining the microhardness of metallic and other inorganic coatings. This method is applicable where indenter forces generally need to be below 10 N, e.g., for electrodeposited coatings, autocatalytic coatings, sprayed coatings and anodic coatings on aluminium. It is applicable to measurements normal to the coated surface and to measurements on cross-sections.
