The effect of surface condition on the strength of ceramic specimens

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

Conclusions

  1. 1.

    The investigation was concerned with the dependence of the bending strength of zirconium carbide microspecimens with varying degrees of porosity on the surface condition after electrospark cutting and mechanical finishing with abrasive powders.

  2. 2.

    It is shown that electrospark machining forms microcracks and cleavage steps in the surface layer of zirconium carbide; these are a characteristic of brittle fracture and cause stress concentrations. These stress concentrations result in a considerable reduction in the strength of the specimens, and this reduction increases with increasing material density and rate of stock removal in machining. The removal of the damaged layer by grinding increases the strength of specimens by approximately 50%.
