Abstract Plasma-sprayed zinc oxide reinforced hydroxyapatite (HA-ZnO) coatings are developed on Ti13Nb13Zr (Titanium) alloy at three levels (4, 8, and 12%) of weight percent (wt%) of ZnO powder to improve the mechanical properties as well as the corrosion resistance. On increasing ZnO reinforcement, the results reveal that the hardness of the surface increases while the surface roughness of the samples continues to fall. The bare Ti13Nb13Zr alloy shows the hydrophobic behavior, however, all the coated samples are hydrophilic and result in a boost to clinical performance. The titanium substrate coated with HA+12% ZnO has the highest corrosion resistance among all the samples.

通过等离子喷涂 HA/ZnO 涂层改善 Ti13Nb13Zr 钛合金的表面性能和耐腐蚀性，用于生物医学应用

摘要 等离子喷涂氧化锌增强羟基磷灰石 (HA-ZnO) 涂层是在 Ti13Nb13Zr（钛）合金上以 ZnO 粉末的重量百分比 (wt%) 的三个水平 (4、8 和 12%) 开发的，以提高机械性能：以及耐腐蚀性。结果表明，随着 ZnO 增强的增加，表面硬度增加，而样品的表面粗糙度继续下降。裸露的 Ti13Nb13Zr 合金显示出疏水行为，然而，所有涂层样品都是亲水的，从而提高了临床性能。涂有 HA+12% ZnO 的钛基体在所有样品中具有最高的耐腐蚀性。
