钛合金微弧氧化羟基磷灰石生物活性涂层的摩擦磨损性能研究

摘要

Took micro-arc oxidation welding technology, bioceramic coating containing hydroxyapatite (HA) was in-situ synthesized on Ti alloy, the friction and wear properties of the bioceramic coating were studied. The affecting discipline such as wearing time and electric current density and their laws were obtained in the experiment. The results showed that the friction coefficient of bioceramic coating containing hydroxyapatite was first increased and then decreased with the friction time, while the friction coefficient was first decreased and then increased when electricity density increased.%采用微弧氧化技术,在钛合金表面原位合成含有羟基磷灰石的生物活性陶瓷涂层,研究了陶瓷涂层的摩擦磨损性能,得出了不同磨损时间和不同微弧氧化电流密度对陶瓷涂层耐磨性的影响规律.结果表明,含有羟基磷灰石的陶瓷涂层,其摩擦因数随摩擦磨损时间的增加而先增大后减小,其耐磨性随微弧氧化电流密度的增加而先减小后增大.
