【Abstract】 The service status and existing questions of turbine facing plate were introduced. The wear_resistance performances of a new facing plate material Polyolefine-metal were compared with those of other materials. The results show that the facing plate compounded Polyolefine and metal has good wear_resistance performances,size stability,mechanical strength and machinability,and the reliability of fitting the facing plate on head cover and bottom ring is ensured.更多还原
