Biocompatibility of implants made of steel 12X18H9T, steel 12X18H9T coated with titanium and hafnium nitrides, and steel 12X18H9T coated with titanium and zirconium nitrides was studied in rats. Implants that represented pins 8-10 mm long and 0.5 mm in diameter were inserted intramedullary into the middle third of the tibia after drilling. The ends of pins were turned down and placed under the skin. The wound was sutured tightly. Dynamics of body weight and temperature as well as the condition of the hair, eyes, oral and nasal mucosa were assessed on days 10, 30, 60 and 90 after implantation. It was shown that implants coated with titanium and hafnium nitrides caused minimum systemic and local reactions while implantation of pins coated with titanium and zirconium nitrides resulted in the development of more pronounced inflammatory changes on both the local and systemic level.

Sputter Deposited

By means of dc-reactive sputtering, it is possible to vary the stoichiometry of deposited zirconium nitrides, by varying the molar fraction of N2 in an Ar–N2 gas mixture. In order to understand the origin of this effect, a theoretical model of reactive sputtering is devised. It is based on the study of reaction kinetics taking place at the surfaces of the cathode and the chamber walls. In fitting the model with experimental data, it turns out that one has to introduce the roles of Ar, N2, and N species. For reactive sputtering of ZrNz films, a good fit is obtained when it is assumed that the molar fraction of N is constant when the molar fraction of N2 increases up to about 75% (under our experimental conditions). Above this concentration of N2, the concentration of N has to increase. By the analysis of the theoretical model, general scaling laws between experimental parameters (current, pressure, and areas of the cathode and the chamber walls) are easily obtained.
