摘要：

A CeF3 compact with 10% silver in volume on the substrate of Hastelloy C was prepared in the paper. Effects of abrasive paper on the composition and surface roughness of the compact were studied. The effect of silver on the sliding friction and wear behavior of CeF3 compact at temperatures to 700 degrees C in air was investigated. By adding 10% silver in volume in CeF3 compact, the sliding friction behavior of the compact could be greatly improved. The friction coefficients were quite low below 300 degrees C. At 400 degrees C, the friction coefficient was higher than that of without silver addition. At 700 degrees C, silver and CeF3 had a synergetic effect on reducing friction, where the friction coefficient was as low as 0.11. The use of silver can prevent the compact from severe damage by forming a thin solid film on the worn surface. (C) 1998 Elsevier Science S.A.
