黄铜化学着色膜层制备及表征

Preparation and Characterization of Film by Chemical Coloring on Brass

采用3种黄铜表面化学着色工艺,分别在黄铜表面得到了黑色、红色和银白色膜层。用SEM观察了膜层的表面形貌,用EDS对膜层进行了成分分析,用XRD对膜层进行了物相分析,并测试了着色黄铜的耐蚀性和结合力性能。实验结果表明,3种着色黄铜的耐蚀性较好,且着色膜层与基体结合良好。

Three techniques of chemical coloring on brass surface were studied.A fine black,red and silvery white plating on brass and zipper were obtained by experiments.The morphology,composition of the tin plating were investigated by the SEM,EDS and XRD techniques.The results of the performance measurement showed that the coating has fine corrosion resistance and binding force by man-made corrosion test,coating binding force test.
