The object of research is metal-cutting tool of steel with multicomponent diffusion coverings based upon transitive elements Cr, Ti, V, Mn. The purpose of job is to increase the serviceability of complex metal-cutting tool by means of plating with multicomponent diffusion coverings based upon transitive elements of the first group Research receptions. Theoretical and experimental researches. The development of the common recommendations on use of the tool with coverings was carried out on the basis of rules of chemistry, physical metallurgy, theory of cutting of metals, theory of mathematical planning of experiments. The experimental researches were spent with use of the modern measuring equipment, the received results were processed by means of the modern computer. Opportunity of use metal-cutting tool of lowalloy steel, modified by multicomponent diffusion coverings for the first time is proved. The way of increase of serviceability of metal-cutting tool by means of multicomponent diffusion coverings plating based upon Cr, Ti, V, Mn by a CVD method is advanced.
