Electric spark treatment of VT20 titanium alloy with T15K6 hard alloy

The results of experiments aimed at studying the composition, structure and properties of electric spark coatings on samples of VT20 alloy with electrodes obtained from sintered powder material made by processing substandard tools made of T15K6 hard alloy by electrodispersion are presented. It is noted that as a result of electric spark treatment of VT20 alloy samples with a T15K6 alloy electrode, the composition, structure, physical, chemical and mechanical properties of the surface layer changed, which made it possible to obtain coatings with improved performance characteristics.
