| 摘 要： | 研究了热处理温度对硬铬镀层性能的影响.发现经过200～300℃1*#h热处理,镀层硬度明显提高,耐磨性得到改善,但硬度和耐磨性的最优点对应不同的热处理温度.对镀层XPS分析表明,热处理过的镀层中有有机碳化物析出.对镀层的EDAX分析表明,热处理使镀层表面氧含量增高,但对镀层微裂纹数量和宽度没有明显影响.对镀层的XRD实验结果表明,热处理后镀层的晶体结构未发生改变.

| Abstract: | Microhardness and wear resistance of a hard chromium coating obtained with a solution containing organic additive were investigated as a function of heat treatment temperature. Meanwhile, XPS, EDAX and X-ray diffraction analyses were conducted to reveal the underlying micromechanism. It was found that: (1) the microhardness and the wear resistance both were significantly improved when the coating was heat-treated at 200℃~300℃ for 1 hour; (2) the content of carbon element within coating was rather high; (3) no changes in crystal structure could be detected for the heat-treated coating. Based on the above results,it was suggested that some sort of organic carbonides must be generated during the heat-treatment, which should be responsible for the properties and improvements. |
