CALCIUM-PHOSPHATE BIOLOGICALLY ACTIVE COATING OF IMPLANT AND METHOD OF DEPOSITION Russian patent published in 2011 - IPC A61L27/06 A61L27/32 A61F2/02 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment. What is described is a calcium-phosphate biologically active coating of an implant which refers to medical equipment, namely, to biologically compatible coatings exhibiting the osteointegration properties, and can be used in dentistry, traumatology and orthopaedics for manufacturing of high-loaded bone implants of various structural materials, e.g. stainless steel. The coating is double-layer. A base made of a structural material is coated with an intermediate layer of the thickness 5-50 mcm made of a valve metal, e.g. titanium. The next layer of calcium-phosphate compounds is generated by an electrochemical method of titanium anodising in a phosphoric acid solution with added calcium compounds to over-saturation in a spark or arc discharge mode. An intermediate titanium layer is formed in continuous vacuum-arc discharge plasma.

EFFECT: method of calcium-phosphate biologically active coating deposition on the implants made of metal structural materials is simple, fast and efficient.
