No. A PVD coating is not scratch-resistant. However, as a rule, PVD coating is more scratch resistant than the surface of the underlying material, usually stainless steel or titanium. The coating is only applied on the surface, so there is a possibility that it will be damaged when subjected to mechanical stress, revealing the base material. Such damage can be caused by harder materials, such as the minerals present in a plaster, or with other harder materials.
