摘　　要：在含氨基缩合物添加剂的处理溶液中制备了高耐蚀性散热膜层。研究了热膜层的沉积条件对散热系数的影响。采用SEM、EDS对膜层的微观形貌及性能进行了研究。结果表明,散热膜层钝化后能耐盐雾实验320 h以上,且膜层无裂纹。High corrosion-resistant and radiating films were prepared in ammoniac condensation addition treatment solution. The optimum ranges process parameters and the additive content were studied by radiating performance tests. The phase composition and properties of the film were studied by SEM and EDS. The results show that the films do not corrode after 320 h salt spray tests. The coating has not any cavities and cracks.
