Title :
Study of coatings obtained by electron beam melting of TiN, TiC, TiB2, δ-MoB powders on titanium base
Abstract :
The specimens were prepared by melting the TiN, TiC, TiB2 , δ-MoB powders and its mixtures on technical titanium, α- and α+β titanium alloys by electron beam melting. The initial powders and coatings were investigated by means of X-ray diffraction. The structures of coatings from more complex mixtures on different base materials depended on the combination of treatment parameters: the thickness of initial powder, the quality of fluxes, and the electron beam current. The interaction of alloying elements and their mutual influence on polymorphism of Ti also determine the phase content and the structure of the coatings
