中图分类号:TQ 153.1 文献标识码:A Effect of content of tungsten on hardness and wear resistance of electroless Ni-W-P plating on aluminium alloy HU Yong-jun, XIONG Ling, MENG Ji-long (College of Mechanical Engineering, South China University of Technology, Guangzhou 510641, China) Abstract: The wear resistance of electroless Ni-W-P coatings on aluminium alloy......
content of RE, the wear rate of cast steel reduced at first and then increased. By adding 0.05%(mass fraction) RE, the cast hot-forging die steel with optimum thermal wear resistance was obtained, which was better than that of H13 and 3Cr2W8V. The large amount of coarse inclusions, (RE)2O2S, resulted from excessive RE, which obviously deteriorated thermal wear resistance. The mechanism of thermal wear......
