Experimental study of the effectiveness of the use of implant coatings based on superhard compounds

The first stage of studies on the biocompatibility of implants made of copper, steel 12XI8H9T, steel 12XI8H9T coated with titanium nitride and hafnium nitride, and steel 12XI8H9T coated with titanium nitride and nitride zirconium was conducted. Experimental studies on white rats have shown that by using implants made of steel coated with titanium nitride and hafnium nitride, reactive changes of soft tissues are less severe.
