Protective Coatings on Steel Tytanoalitovani 40X13

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.
