• The presence of the bioactive glass layer could produce a strong biological bond between the bone and the prosthesis, improving the stabilisation of the prosthesis itself. While in thepast RKKP bioactive process has been tested in order to deposit RKKP bioactive glass on zirconium oxide and titanium substrates. The characteristics of the obtained coating have been compared with the ones of a RKKP coating obtained by painting. The samples have been submitted to metallographic inspection in order to determine the structure of the coating, roughness determination and adhesion test according to standard ASTM C633-79. While the deposits obtained by painting, show very smooth surface and diffusion in the substrate material, plasma sprayed RKKP coatings show high roughness and porosity and good adhesion to the substarte, which seems to be suitable for bone cells adhesion.

• Biocompatible materials are considered very promising and important for biomedical applications, particularly for endoprostheses performance improvement. In the specific research field that is concerned with coating materials for endoprostheses a significant attention is given to materials, which can be deposited on the structural prostheses and implants materials such as titanium, titanium alloy, stainless steel, CoCrMo alloy or ceramic substrates, with the specific purpose of producing a surface that increases the osseointegration capabilities of the prosthesis. In this field interesting materials could be bioactive ceramic glasses in particular as coating material of zirconium oxide and metallic substrates. The principle, which drove the present research, was the production of a bioactive glass layer on an inert substrate, suitable for its mechanical resistance and suitable elasticity, with the purpose to produce a suitable surface where the bone could adhere.
