Abstract
The resource-saving technology has been developed for pulse-plasma hardening of tools. The technology is characterized by low consumption of alloying elements and electric power and high productivity (up to 0.5 m²/h). It allows hardening (heating) of only the working (cutting) surfaces, which leads to an increase in wear resistance without any change in structural state of a workpiece as a whole. Power consumption of the machine is 10 kW.
Keywords: surface hardening, alloying, pulse plasma, technology, equipment, metal cutting tools, dies, blanking dies, calculation, efficiency, experimental studies
