Bioceramic coating of a metal-containing substrate

Highlights

The present invention relates to the chemical process of coating a bioceramic material on a surface of a substrate. Materials implanted in vivo essentially have direct contact with the human body through the interface between the implant surface and bones, tissues and extracellular body fluids. Major issues related to surface modification processes include corrosion and wear resistance of the implant, biocompatibility and bioactivity, which in turn lead to premature implant failures, debilitating pain and surgical revisions. The proposed process enhances the performance of implants.

Technology transfer

This technology is available for licensing. There is an opportunity for this invention to be developed for particular applications and for demonstration of the final product through a collaborative research project. The business opportunity may be referred to by its NRC ID: 11805.

Market applications

Applications for this technology are of interest to the healthcare sector, in particular to the field of fabrication of prostheses for the replacement of bone tissue.

How it works

A process for coating a surface of a metal-containing substrate with a bioceramic material includes activating the surface of the metal- containing substrate by applying a voltage to the substrate in a liquid containing an electrolyte and immersing the substrate in a deposition solution containing the bioceramic material of precursors for the bioceramic material. The coated substrate may be heat treated to enhance coating bond strength.
