摘要：
The present research is aiming at the development of new Fe-base wear resistance alloy, which has been expected to the substitute for Stellite 6 in nuclear power industry. The effects of Cr and C addition on the wear resistance were investigated. The sliding wear tests were performed in air at the temperature range 25-300 degreesC, and also in pressurized water at 25-250 degreesC. The contact stress was 103 MPa in accordance with current nuclear power plant component designs. The composition of Fe-base alloy was optimized to improve the wear resistance. The sliding wear behaviors of the optimized Fe-base alloy and Stellite 6 were compared in the present study. The weight loss of new Fe-base alloy after 100 cycles sliding wear test was found to be smaller than that of Stellite 6. (C) 2003 Published by Elsevier Science B.V.
