BIOACTIVE SURFACE LAYER, PARTICULARLY FOR MEDICAL IMPLANTS AND PROSTHESES

摘要

The bioactive surface layer is particularly suited for medical implants and prostheses. A variable portion of the 0.1 to 50.0 .mu.m thick, porous surfac e layer is comprised of calcium phosphate phases. The surface layer contains amorphous or nanocrystalline calcium phosphates and the pore density on the surface of the surface layer ranges from 104 to 108 pores/mm2. The ratio of Ca/P over the entire surface layer ranges from 0.5 to 2.0. The surface layer has a high solubility so that it can act as a contributor of calcium phospha te for the formation of bone.
