The work is devoted to the developmentof composite materials and coatings with high wear- and corrosion-resistance on the base of titanium-chromium carbide and diboride with metal binder by physical-chemical studies of the adhesive interaction as well as structure and study of mechanical and tribotechnical properties of gas-thermal spraying and electro-spark alloying coatings.

In this work have been solved the importantscientific and technical problems – increase durability of machine parts working in conditions of friction-slip without lubrication and fretting-corrosion.

The scientific bases and the methodology of choice:the composition of the metal binders for composite materials based on titanium-chromium carbide and diboride; material composition, kind and modes of coatings for dry friction at different speeds and loads and for fretting-corrosion.

Developed and tested new composite materialsfor their application in plasma, detonation and electro-spark coatings with high wear resistance; developed and tested technology of hardening: aeronautical engineering parts (chassis components, the guide flaps), working in the conditions of fretting-corrosion, intense friction; machine parts for papermaking and printing equipment; nozzles of liquid blasting equipment.

On the world levelindicate achieved indicators of wear-resistance by developed of coatings.
