Preparation of porous parts from chromium carbide with the aid of volatile fillers

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Summary

The influence of chlorides on porosity variation during the sintering of chromium carbide specimens was examined. Chromium chloride must be regarded as the most effective pore-generating addition, the optimum quantities of the additions investigated being 2–4% CrCl3 · 10H2O, 6–8% CoCl2 · 6H2O, and 1–2% NiC12 · 6H2O.

Because of the activating effect of the chlorides, to obtain chromium carbide specimens of equal or even higher strength it is possible to lower their sintering temperature by 200–300°C compared with that required for similar specimens containing no additions. The maximum residual porosity attained is 50–52%.
