This report covers the first three years of the contract entitled ''Development of a Theory of Wear of Ceramics'' (DOE--ORNL Project Authorization /number sign/19x-15, Basic Agreement No. 7802). The research work carried out during this period includes: (1) the exploration of the hotspots and the triboluminescence generated by a sliding contact between a sapphire disk and ceramic pins, (2) the use of an infrared scanning system (AGA Thermovision 750) to measure the contact temperature between a sappphire disk and ceramic pins, (3) installing a new infrared scanning system (Inframetrics model 525) with a digital video processor (Quantex DS50) and a computer for temperature measurement, (4) preliminary wear measurements under a controlled environment for a PSZ pin sliding against a sapphire disk, (5) measurements of mean wear depth of hotspots of Si3N4 sliding against sapphire, and (6) developing a thermomechanical wear theory. These topics will be discussed respectively below. 11 ref., 14 figs., 12 tabs.
