Coatings based on aluminium nickelides and Ti 2 AIC Ti 3 AlC 2 MAX-phases are obtained by the method of self-propagating high-temperature synthesis. The processes occurring in the powder mixture of nickel and aluminium, as well as in the titanium-aluminium-carbon mixture are studied. The effect of the thickness of the coating on the maximum temperature and velocity of combustion wave is found. The coating consists of small crystals NiAl, Ni 3 Al or Ti 2 AlC, Ti 3 AlC 3 , fused together. The coating has high electrical conductivity and can be used as heat-resistant protective coatings or electric heaters.
