Abstract
A biocompatible material is made of a rust-resistant, alloyed stainless steel which is configured with at least one martensitic surface layer which is formed by a heat treatment with nitrogen case hardening and subsequent cooling. The surface layer, orthogonally to the surface into the sample interior, displaying a virtually linear course of the accompanying hardening and being achieved by a complete phase change (so-called austenitising) in the structural state from ferrite via austenite to martensite. In addition, the biocompatible material is in contact preferably indirectly or directly with the human body, no reactions and/or sensitivity problems being able to occur even in permanent use as a result of its absolute freedom from nickel.
