Abstract

A method for surface working a tribological coating of a supereutectic aluminum-silicon alloy or an aluminum-silicon composite material with a coating structure includes machining the surface dry, without lubricant, in a one-step process, with a cutting tool having a cutting material containing diamond. The surface treating may be followed by a one-step finish honing or one-step texturing process.
