This document specifies a method for testing the wear resistance and friction coefficient for fine ceramic thin films in dry and high-humidity environments, where such films have a thickness of up to approximately 1 Āµm and are deposited on a substrate or a base, including a thin substrate or a very thin organic polymer film base.
