| 目的 研究 CuSO4 浓度和微弧氧化工艺参数(电压、氧化时间)对 TC4 钛合金微弧氧化膜颜色及性能的影响。 方法 在磷酸钠电解液中,对 TC4 钛合金进行微弧氧化处理,并添加 CuSO4 获得不同颜色的陶瓷膜,对氧化膜的宏观形貌、微观形貌、物相结构以及硬度进行分析。 结果 添加 CuSO4 能使陶瓷膜颜色变深,随着 CuSO4 浓度升高,膜层由灰色逐渐变为红褐色。 当 CuSO4 质量浓度为 0. 5 g/ L 时,氧化膜表面均匀致密,显微硬度最高(627. 1HV);当 CuSO4 质量浓度为 1. 5 g/ L 时,氧化膜显微硬度最低(382. 8HV)。 随着电压升高,膜层颜色加深,色泽更均匀,但表面硬度下降。 在 400 V 条件下制备的氧化膜硬度最低,但是色泽最均匀。 随着氧化时间的延长,氧化膜厚度增加,颜色加深,色泽更为均匀,但是当氧化时间超过 15 min 后,氧化膜颜色变浅。 结论 CuSO4 对微弧氧化膜的显色作用明显,其浓度及微弧氧化工艺参数(电压、氧化时间)均对涂层性能、色泽、致密性、厚度及相组成具有很大的影响。 |

| Objective To investigate the effect of CuSO4 concentration and micro-arc oxidation process parameters (voltage, oxidation time) on the color and properties of the micro-arc oxidation coating. Methods TC4 titanium alloy was treated in sodium phosphate electrolyte to obtain a surface ceramic coating by using micro-arc oxidation technology. The macroscopic and microscopic morphology, phase structure and hardness of the oxidation coating were analyzed. Results By adding of CuSO4 of different concentrations, the color of coating samples was darkened which turned from gray to red-brown when the CuSO4 concentration was increased. The surface coating was uniformly dense with the highest microhardness of 627. 1HV when the concentration of CuSO4 was 0. 5 g / L. And the coating microhardness was decreased to the lowest 382. 8HV when the concentration of CuSO4 was 1. 5 g / L. With the increasing of voltage, the color of coating got deeper and more uniform, while the coating hardness decreased. The hardness of coating was the lowest and the color was the most uniform at 400 V. When the oxidation time was prolonged, the coating thickness was increased and the color became deeper and more uniform. However, the coating color tended to be lighter when the oxidation time was over 15 min. Conclusion CuSO4 has significant coloration effect on micro-arc oxidation coating and the concentration and process parameters (voltage, oxidation time) have great influence on performance, color, density, thickness and phase structure of the coating. |
