Abstract

Past studies on application to the surface of steel 40X13 multi tytanoalitovanyh coatings in containers of consumable shutter using a mixture of powders of titanium, aluminum; titanium hydride; tytanoalituvannya steel 40X13 with pre-deposited TiN layer; tytanoalituvannya pre-nitrided steel among ammonia. The possibility of forming coatings on steel 40X13 involving compounds Ti₄Fe₂O, FeTiAl, TiN, TiC and transition zone. Established distribution of chemical elements and microhardness thickness diffusion coatings. The maximum microhardness detected for layers Tees - 31,0-34,0 GPa; TiN layers for - 19,5-22,5 GPa; for the zone Ti₄Fe₂O, FeTiAl - 5,0-7,0 GPa.
