Mechanical and corrosion properties of Ta–Mo coatings by heating processes

In this research, substrate heating process has been used for the production of Ta–Mo high temperature protective coatings. The microstructures of the alloy coatings have been studied through X-ray diffraction and scanning electron microscopy. Mechanical and corrosion properties of different alloys have been investigated in both low and high temperature heating processes. Substrate heating processes (from 250 to 550°C) were expected to produce partially recrystallised and fully recrystallised microstructures. Higher heating temperature results in recrystallised microstructures, but adversely affects the density of atoms V_t and bond energy G. The behaviour of low and high temperature heating processes on corrosion and mechanical properties of Ta–Mo nanostructured coatings was studied.
