Combustion of a high-calorific thermite mixture on the surface of a titanium substrate

Abstract

The combustion and chemical transformation of highly exothermic MoO₃/NiO/Al/C andMoO₃/NiO/Al/B mixtures on the surface of a titanium substrate under centrifugal acceleration are studied. It is shown that chemical reactions occur not only in the combustion wave, but also on the surface of the titanium substrate, between the combustion products and the substrate material (titanium). The dynamics and mechanism of formation of layered (gradient) titanium–ceramics materials (Mo–Ni–C–Ti or Mo–Ni–B–Ti) is investigated.
