| 摘 要： | 线材拉拔加工正向精密、高速、低耗、高生产效率方向发展，金刚石涂层拉拔模具是最受用户青睐的产品之一。在综述直流电弧等离子体喷射技术制备金刚石涂层拉拔模具方法的基础上，利用洛氏硬度计、表面粗糙度轮廓测量仪、拉曼光谱仪和光学显微镜进行涂层质量检测。检测结果显示:金刚石涂层的纯度和厚度均匀性均较好；在1 470 N载荷下薄膜压痕的边缘区域无严重裂纹及薄膜脱落现象, 其表面粗糙度Ra平均值为18 nm。

| Abstract: | Wire drawing process is developing towards precision, high speed, low consumption and high production efficiency. Diamond coated drawing die is one of the most popular products. On the basis of summarizing the drawing die method of diamond coating prepared by direct current arc plasma jet technology, the coating quality is tested by Rockwell hardness tester, surface roughness profilometer, Raman spectrometer and optical microscope. The results show that the purity and the thickness uniformity of diamond coatings are both good. There are no serious cracks or film shedding at the edge of indented area under 1 470 N load. The average surface roughness Ra is 18 nm. |
