Abstract
The solid solution hardening is applied to the qualitative improvement of alumina materials. Titanium oxide is occluded in alumina materials by thermal diffusing addition method of which alumina sample is put into the titanium oxide powder and is heated in electric furnace. By these treatment, when the amount of titanium oxide content in the layer of the alumina oxide material is about 0.8%, the Vickers hardness number of the layer increase maximum two times as much as non-treated one. The white corundum, alumina ceramic cutting tool, alumina ceramic and single crystal Al2O3 (white sapphire) are drastically hardened by above methods, the static friability of the abrasive grains is increased and the friction wear of the abrasive grain on rotating cylindrical bearing steel is decreased and the wear of the cutting tool is restricted.
