【Abstract】 The technique of Ni-P alloy chemical deposition on copper alloy surface is studied,and the influences of technical conditions,aging temperature and aging time of the technique on the crystallization and hardness of coated layer and the bond between matrix and coated layer are investigated. The results show that the surface hardness, wear resistance and corrosion resistance of the copper are obviously improved by Ni - P alloy chemical deposition.更多还原
