Electrospark alloying of titanium and its alloys: The physical, technological, and practical aspects. Part I. The peculiarities of the mass transfer and the structural and phase transformations in the surface layers and their wear and heat resistance

A detailed analysis of the works concerning the electrospark alloying of the surface of titanium and its alloys to improve their physicochemical properties and performance characteristics has been carried out. It has been shown that the electrospark alloying method makes it possible to enhance some important features of titanium such as its wear resistance, heat resistance, and corrosion stability.
