Sirovatka V. Development of protective detonation coatings of mechanical alloying powders based on system Ti - Al.

Object of research - protective detonation coatings of mechanical alloying powders based on system Ti-Al. The purpose of work - development of new coatings and materials on basis titanium aluminide with best properties, research and an esteblishment of phase and structural transformations at mechanical alloing titanium aluminide, a choice of structure and mode of drawing of coatings which provide parameters of heat resistance and tribotechnical properties. Methods of research - microrentgenospectrometery, electronic scan microscopy, optical microscopy, X-ray, tribotechnical test. The phase formation of the detonation coatings from the powders Ti-50Al was investigate. The powders of alloys were prepared by crushing of ingot mechanical alloying of the elementary powders Ti and Al. The application of the poliphase powder materials which were activated by the mechanical alloying did the phase formation process of coatings more universal and guided, due to more active and sentive reaction of materials witha gas environment. The carried out attestative test of the developed coatings on ,,ЮЖМАШ" and ,,Инмед" have show, that the developed coatings can be used as substitutes Co and Ni.
