FIELD: metallurgy.
SUBSTANCE: steel tool or carbide tool treatment method involves application of diffusion coating by saturation of steel or carbide tool in eutectic lead-lithium melt with addition of copper and nickel so that the coating is obtained. After application of coating the tool is strengthened by its being aged on material with hardness of 10 to 18 HRCe at value of contact stresses of 2000 to 5000 MPa during 2-5 minutes.
EFFECT: obtaining the coating having high stability to adhesion hardness, mechanical abrasion and deformation at maintaining positive operating properties of nickel-copper coating.
