中文摘要：以液压支架立柱常用材料27SiMn为基体，在Ni-P化学镀的基础上加入稀土硫酸高铈。通过正交试验对施镀工艺参数进行优化，以镀速为评定指标，获得了化学镀Ni-Ce-P的最优工艺配方，并对最优工艺条件下得到镀层的形貌进行了分析。结果表明：含有40 mg/L硫酸高铈的最优配方下的镀速为33.38 μm/h；相对于二元Ni-P镀层，加入稀土得到的镀层胞状结构更细小，表面更加平整、致密。
英文摘要：Based on the mining hydraulic support column 27SiMn, the cerous sulfate was added to the electroless Ni-P solution. The plating velocity was used as an evaluation indice, the optimum technology was obtained by orthogonal test. At the same time, the morphology of the plating obtained at the optimum technology was analyzed. The results show that the plating velocity reaches 33.38 μm/h under the condition of the solution containing 40 mg/L cerous sulfate. Compared with the electroless plating Ni-P coating, Ni-Ce-P plating surface becomes more compact and smooth.
