EFFICIENCY of TREATMENT of HARD-TEMPERED of chromium structural STEEL of CUTTING TOOL With coating

G.I. Kostyk, O.M. Melkozerova, R.W. Voropay, A.A. Breus

Dependences of the removed volume of a material for an operating time from deterioration on a forward and back surface and hole CT are resulted the size. It is rotined on the example of treatment of hard-tempered chromium of structural steel, that one criterion of efficiency of treatment hard-tempered steels CT with coating not enough, and it is necessary to use a multicriterion estimation – total rating, taking into account the size of the taken off volume of material for period of durability, durability of CT and productivity of treatment. It is rotined, as possible to choose the modes of treatment and material of CT with coating providing high total rating, take into accout adhesion.

Keywords: hard-tempered steel, taken off volume, to time durability CT, productivity of treatment, adhesion.
