 A true PVD coating is harder than steal, based on the chemical matrix that has a ceramic component.  It has been used for years in F1 as a low friction coating and moved globally into industrial tooling.  It makes tooling's last about 900% longer and in most cases can reduce friction to a point to where no cutting solution is needed (dry cutting).

It may not maintain its perfect visual finish, but it has allowed an evolution in the tooling industry and racing that is impressive.  In my opinion it is the single most important technical advance since the use of cryogenic freezing of metallic components to relieve internal stresses caused by the metals manipulation.
