摘　　要：利用化学沉积方法在铝合金表面制备镍-磷合金镀层。讨论工艺参数对合金镀层表面形貌、相结构及耐蚀性的影响。结果表明:温度对合金镀层表面形貌的影响较大,而对相结构的影响较小。在84℃下获得的合金镀层具有较好的耐蚀性。Ni-P alloy coatings were prepared on aluminum alloy surface by electroless deposition. Influences of parameters on the morphology, phase structure and corrosion resistance of the alloy coatings were discussed. Results showed that temperature has obvious effect on the morphology, while has no significant effect on the phase structure. The Ni-P alloy coating obtained at 84 ℃ present better corrosion resistance.
