【摘要】 通过Ni-P化学镀及Ni-P-SiO2(微米)、Ni-P-SiO2(纳米)化学复合镀探讨纳米SiO2颗粒对镀速及镀层性能的影响。结果表明:添加适量的SiO2纳米粒子于镀液中,使镀速上升,所得镀层硬度、耐磨性等性能相对于Ni-P镀层及微米颗粒复合镀层都有显著地提高。更多还原

【Abstract】 The experiments of Ni-P electroless coating and Ni-P-SiO₂ （micrometer）, Ni-P-SiO₂ （nanometer） electroless composite coating were done to study how SiO₂particles affect the coating rate and properties of the film. The results show that coating rate increased, hardness and wear of the film comparing to the film of Ni-P and micrometer particles composite coating are promoted notably　when the nanometer particles SiO₂ were put into the solution.更多还原
