Abstract

The possibility is examined of preparing finely-crystalline powders of tool steel R6M5F3 by the electric hydropulse method for treating molten metal before spraying. It is established that there is a reduction in gases and nonmetallic inclusions. As a result of this there is a reduction in the kinematic viscosity of the molten steel, and an increase in surface tension and the degree of undercooling. These factors promote the preparation of finely-crystalline powder with improved physical and production properties.
