  Ti3AlC2, Ti2AlC, Ti2AlN, Ti2Al(C1-x,Nx)y are representative of nanolaminated ternary carbides called MAX phases of structural type 312 and 211, which combines the best properties of ceramics and metals. The aim of this work was to study resistance during heating in air  by TG and DTG methods of MAX phases of systems Ti-Al-(C,N) structural type 312 and 211. Results of termal stability on the air showed increasing of  layers of titanium carbide phase in the structure MAX increases its resistance to oxidation. The weight gain of the phase structure type 312 during heating up to 1000 ° was 3.5%, and the structural type 211 - 8.5-9.5%. Moreover, the substitution of carbon by nitrogen in the structure 211 causes a reduction in oxidation resistance.
