Abstract

In order to attain selflubrication in a wide range of temperatures Nibased powder metallurgy P/M composites containing different amounts 8–20 wt of Ag were prepared and their friction and wear characteristics were investigated against AISI 52100 steel at temperatures of 25 400 and 600 °C One composite containing 12 wt Ag and 4 wt hBN was also prepared and tested under the same conditions to analyze the effect of addition of hBN on the friction and wear behaviors The composites mainly consisted of Nibased solid solution free tungsten Ag and BN as revealed by XRD and EDS analyses The friction coefficients and wear rates were found to decrease with increasing temperature and amount of silver The friction coefficients shown by the composites containing relatively higher amounts of silver were in the range from 025 to 016 with temperature increasing from RT to 600 °C The wear rates of the Ag/hBNcontaining composites were approximately an order of magnitude lower than those of the Base Alloy having no solid lubricant at all the temperatures The addition of 4 wt hBN resulted in slightly greater friction and wear in comparison to the composites containing only silver
