| 目的 研究不同电压、电流和氧化时间下,钽表面微弧氧化陶瓷层的生长机理与耐磨性能的变化。 方法 通过微弧氧化技术在钽金属表面制备陶瓷层,并采用扫描电子显微镜观察陶瓷层的表面形貌,采用摩擦磨损试验仪对陶瓷层的摩擦学性能进行研究,探讨放电电压、放电频率、氧化时间对陶瓷层摩擦系数的影响。 结果 在电压 400 V、频率 1000 Hz、氧化时间 20 min 条件下获得的陶瓷层表面质量最好;在电压 350 V,频率 1000 Hz,氧化时间 10 min 条件下获得的陶瓷层耐摩擦性能最好。 结论 对钽金属表面进行微弧氧化处理,可以显著降低钽金属表面的摩擦系数,提高耐磨性能。 |

| Objective To study the formation mechanism and the change of wear resistance performance of micro-arc oxidation ceramic coatings on tantalum under different experimental circumstances. Methods Ceramic coating on the surface of tantalum metal was prepared by micro-arc oxidation technology. The surface profile of coating was studied by SEM. Moreover, the influence of experiment parameters like voltage, current and duty cycle, frequency on the abrasion resistance of ceramic coating was investigated in details. Results The best surface quality performance was observed under the set of parameters as follow: 400 V, 1000 Hz, 20 min; the best wear resistance performance was observed under the set of parameters: 350 V, 1000 Hz, 10 min. Conclusion The tantalum metal surface by micro-arc oxidation could obviously reduce the friction coefficient and improve the wear resistance of tantalum metal surface. |
