PROCESS FOR COATING A SURFACE OF A METAL ELEMENT TO INCREASE OSTEOINTEGRATION THEREOF AND PROSTHETIC DEVICE INCLUDING SAID ELEMENT

摘要

A process for coating a surface of a metal element, in particular a metal element of a prosthetic device, comprising: providing an electrolytic bath comprising: at least one collagen, calcium ions and phosphate ions; immersing into said electrolytic bath at least one cathode and at least one anode, said at least one cathode comprising the metal element to be coated; applying electric direct current to said electrolytic bath so as to obtain on said surface an electrolytic co-deposition of collagen with a calcium-phosphate compound comprising hydroxyapatite. The coating layer thus obtained has a high biocompatibility, so as to obtain an interface between metal element and bone structure which enables a faster new bone formation and a bone integration strengthening in time.
