Synthesis methods and techniques for strengthening the working surfaces of machine parts with new qualitative and quantitative characteristics is one of the promising areas of strengthening the development of modern technologies.
For machine parts perspective is a combination of two or more methods of diffusion saturation. Such treatment including special modes enables diffusion hardened surface layers of great hardness and low brittleness that work well in harsh operating conditions [1-3].
We have developed a new complex method of strengthening surfaces of machine parts and tools. The method consists of chemical vapor deposition and diffusion saturation titanium and chromium.
Depending on the formulation of chemical coatings obtained strengthened diffusion layers of different morphology and the values of physical and mechanical characteristics.
Application of complex method significantly extends the possibilities of obtaining various diffusion coatings with the necessary characteristics to perform certain tasks for hardening parts of machine parts and tools.
