METHOD FOR BIOMIMETIC GROWTH OF CALCIUM PHOSPHATES CERAMICS ON METAL IMPLANTS

摘要

The objective of the present invention to provide a method for growth of calcium phosphates ceramics (CPs) on metal implants, particularly on Ti and Ti-alloy implants, that generates thin and durable coatings of metal implants without the limitation of other techniques known in the art. This objective is achieved according to the present invention by a biomimetic method for which comprises the following steps: a) a combination of mechanical, chemical, and thermal treatments in order to generate an appropriate grafting layer on the metal implant; and b) a coating procedure of the treated metal implant by controlled CaPc precipitation. The results demonstrated that metal implants can be efficiently coated with CaPc in a short time using a wet method, offering unprecedented opportunities. This wet route is carried out at almost room temperature, at low cost, with an environmental-friendly method with low energy consumption, and in a short time. According to the invention, an innovative and extremely competitive method for coating of metal implants with CaPc is claimed.
