NiAl intermetallic is obtained during exothermic reaction of mechanically activated Ni and Al powders, taking place by thermal explosion (TE) mode of self‐propagating high‐temperature synthesis (SHS). When a layer of Ni–Al blend is placed in contact with Ta substrate, the heat this exothermic reaction results in reaction multilayer with composition corresponding to intermetallic predicted by Ta–Ni–Al ternary phase diagram. The used approach is proposed for processing of oxidation resistant coating on Ta as well as for joining of parts from ta and its alloys.
