Mechanical properties of carbon coatings, doped by carbide-forming metals

Microhardness, modulus of elasticity, internal mechanical stresses, tribotechnical properties of chromium and titanium-doped carbon coatings are determined. It is shown that doping with carbide-forming metals of carbon coatings allows preserving high microhardness, leads to a decrease in internal stresses in $1.2 \dots 3.2$ times, decays high strengths of the adhesive compound (its maximum value is recorded with chromium alloying) and reduces in more than $2$ times Coefficient of friction in comparison with single-component carbon coatings.
