The effect of fine wear particles as the third body on surface smoothing of alumina is investigated in sliding contact against itself under different normal load, sliding velocity and temperature. Smooth surface formed as a result of wear is composed of the part of original grains and that of agglomerated wear particles. Hardness of the part of agglomerated wear particles distributes widely up to 2,000 kgf/mm2 according to the frictional conditions. The smooth surface geometry is depended on the characteristics of agglomerated wear particles. In unlubricated sliding of alumina against itself at 900°C, mirror like smooth surface of the maximum surface roughness in the order of O-Ol^im is generated as a result of sintering of wear particles on wear surface.
