Provides general information about solid reinforcing materials and steels for rock cutting tools; some problems of efficiency and durability of sintered cermet hard alloys are shown. The possibility of replacing expensive wear-resistant alloys with economically alloyed white cast irons with an increase in mechanical properties, hardness, wear resistance and impact resistance of white cast iron due to the treatment of the melt with nitrogen and an increase in the carbon content is shown. Possible ways of improving the properties of sintered metal-ceramic alloys due to thermal and chemical-thermal treatment are briefly highlighted.
