Characterizing the surface contact behaviour of ceramics - Part 2 Chemo-mechanical effects
Czernuszka JT., Page TF.
The effect of chemical environment (a homologous series of n-alcohols) on the near-surface hardness and wear behaviour of two glass-bonded ceramics has been investigated. A change by upto a factor of two in both these parameters may be observed, with a good correlation between them. The indentation fracture behaviour of one material was also studied, and the environmental dependence of crack length suggests a slow crack-growth mechanism. The results show that the near-surface mechanical properties of ceramics may be modified by environmental means. © 1987 Chapman and Hall Ltd.
