FIELD: metallurgy.
SUBSTANCE: procedure consists in selection of material for coating by value of specific volume energy of plastic deformation considering pressure in friction pair. Further, chosen material with specified values of wear intensity is subjected to plastic deformation of surface under a selected preset mode. Strength characteristics of material of part surface are preliminary analysed. There is selected material of coating depending on a value of coefficient of wetting material of part surface with the most corrosive to surface medium. Wetting coefficient should be within the ranges 0.2-0.9. Successively, there is formed coating of 50 mcm thickness out of chosen material on surface of a part. A required mode of plastic deformation of this material is selected and carried out depending on an optimal value of modulus of deformation resistance of surface layer of parts.
EFFECT: raised resistance of combined mineral coating formed on surface of parts.
