ABSTRACT:
Hard, wear resistant, biocompatible and blood compatible coatings for components of external blood-contacting pumps including mechanical heart devices that are exposed to conditions of wear in the body and that may be exposed to blood components. The components may be fabricated from zirconium or the alloys of zirconium and the coatings comprise either blue-black or black zirconium oxide or zirconium nitride that are tightly adhered to the underlying metal substrate. In the event that the component is used under conditions which subject it to wear, then the coating should have a thickness that provides sufficient residual compressive stresses to withstand these conditions.
