FIELD: metallurgy.
SUBSTANCE: technological coating is applied to some part of surface of each item and the following chemical heat treatment is carried out. Coating of titanium nitride (TiN) is applied using ion-plasma method. For that purpose, each item is arranged in dismountable device providing the access of ion-plasma titanium and nitrogen flows to that part of the item surface, on which titanium nitride coating (TiN) is formed to protect the surface at the following chemical heat treatment.
EFFECT: providing reliable protection of those surfaces of the items and assemblies, on which presence of diffusion coatings formed on working surfaces of those items is not allowed during their chemical heat treatment.
