ESHEL, A. and WILDMANN, M. Wear properties of tungsten carbide and aluminium oxide sintered materials Wear,Vol 12,No 1 (July 1968) pp 1'7-25 Results obtained so far from investigations on the wear mechanism of sintered materials on tungsten carbide or aluminium oxide suggest that the wear of these materials is determined by impact loading and temperature-dependent welding phenomena. At high temperature, healing processes occur which markedly increase the mechanical resistance of both types of material and reduce their wear accordingly. It is assumed that healing processes lead to the relief of internal stresses of the second kind. It was also established that the wear of aluminium oxide is determined by mechanochemical processes.
Salts of aluminium oxide are formed in the presence of organic acids used as surface,-active media. (5 figures, 3 tables, 26 references) (Tribology 1968
