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
