Annotation It has been examined the possibility of obtaining 9ХС and solid steel alloy multilayer coatings BK6 combination of nitriding in ammonia environment followed by titanium-aluminum in a powder mixture in containers with consumable gate. Barrier compositions of TiC, TiN positively effects on the phase and chemical composition of coatings. It also inhibits the formation of Fe(Al) layer on steel 9ХС and areas with a high content of aluminum and oxygen on BK6 solid alloy. Nitrogen plus Titanium calorizing promotes abrasive wear resistance and stability of steel 9ХС, as well as stability of multifaceted carbide indexable BK6 plates.
