Influence of the mechanical-thermal formation technology (MTF) on the properties of a drill-bit combined teeth (CT)
The article considers the possibility of sintering of hard alloys' various carbide-tungsten-cobalt powders on steels with different carbon content. It is found that the strong characteristics, namely, in case of cutting, depend on the mechanical formation staging and, specifically, when the one-stage MTF is 1,6…1,9 times higher than the two-stage ones due to the η-phase elimination in the transition solid alloy-steel zone. As a result, it is claimed that the durability of the combined teeth, obtained by the powders sintering method of tungsten-cobalt hard alloys depends on the mechanical formation staging.
