Abstract:
A combination wear protection film for a component made of a substrate susceptible to wear, the substrate including one of plastic and soft metal, the combination wear protection film comprising:a wear-resistant surface film containing at least one of carbon, nitrogen, silicon and boron, the at least one of carbon, nitrogen, and boron being at least 30% by atomic weight of the surface; and a support film positioned between the substrate and the surface film, the support film having a thickness and providing a transition over the thickness from a relatively soft base level of the support film resting on the substrate to properties of the surface film, the support film being made of a plasma polymer deposited from at least one of a silicon-organic compound, an aliphatic carbon compound and an aromatic carbon compound, the support film having a quasi-continuous transition in modulus of elasticity from a first value of the base level of the support film to a second value of the surface film.
