摘要

We investigate the erosion characteristics of hard alloys in spark alloying and their relation to the physical and mechanical properties. The WC - 16 percent Co alloys used were made by traditional vacuum sintering in the temperature range 950-1350 deg C or by sintering with subsequent high-energy treatment under pressure at the same temperatures. We show that how efficiently protective hard alloy coatings are formed on the substrate depends in more than one way on the porosity and the bending strength, definitely depends on the cracking resistance of the alloys, but is most clearly related to the resistivity which in turn, is determined by the quality of the phase and grain boundaries. In addition, a linear relationship exists beteen the cathode mass gain, the transfer coefficient, and the erosion of the anode material. We demonstrate experimentally that the erosion resistance of hard alloys is a structure-sensitive characteristic to the extent that the structural factors affect the resistance.
