摘　　要：试验研究温度对1060铝合金表面化学镀Ni-P-SiC的影响,着重探讨不同温度对镀速及镀层形貌、成分、耐腐蚀性的影响,并得出最佳镀液温度。结果表明,当镀液温度为90℃时,镀速适宜,镀层组织均匀、细小,镀层与基体结合紧密,耐腐蚀性最强,同时镀层中的SiC含量也达到最大值。The effect of electrolyte temperature on Ni-P-SiC chemical coating at aluminum alloy surface has been investigated. The influence of different electrolyte temperature on de positing velocity, coating morphology, composition and corrosion resistance of the coating lay er has been analyzed particularly. The optimum electrolyte temperature to be used for coating has been found. The analysis results show that when the electrolyte temperature is 900（2 the deposition velocity is equitable, the coating construction is even and fine; the coating layer is closely connected to the matrix alloy; the corrosion resistance is the highest and the SiC content reaches to the highest in the coating layer.
