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