Bio-compatible surface layer

摘要

The layer has an incremental zirconium oxide portion and a decreasing base metal oxide portion along cross sections in a direction of an external surface, where the layer is formed from zirconium oxide and a base metal oxide i.e. titanium, or microporous layer oxide material. The layer exhibits a zirconium oxide concentration of 25 to 80 mass percentage. Thickness of the layer lies from 1.2 to 7.5 micrometer. A porous structure exhibits closed pores in maximum diameters of 1 micrometer. The porous structure exhibits open pores in maximum diameters of 5 micrometer. An independent claim is also included for a method for coating of substrates with base metal.
