This work aims to study the optimal conditions to synthesize hydroxyapatite-multiwalled carbon nanotube (HAp-MWCNT) coatings on Ti6Al4V by electrodeposition technique. The structural behaviors, morphology, and mechanical properties of the coatings were characterized by various advanced methods. The analyzed results showed that the obtained coatings were composed of hydroxyapatite (HAp) and multiwalled carbon nanotube (MWCNT) phases. The presence of MWCNTs in the HAp-MWCNT composite, which improved adhesion between the coatings and the substrate about 2.3 times, increased 20% of hardness and decreased about 40% the solubility of HAp-MWCNTs/Ti6Al4V in comparison with pure HAp coating on Ti6Al4V.

羟基磷灰石-多壁碳纳米管纳米复合材料在 Ti6Al4V 上的电沉积

本工作旨在研究通过电沉积技术在 Ti6Al4V 上合成羟基磷灰石-多壁碳纳米管 (HAp-MWCNT) 涂层的最佳条件。涂层的结构行为、形态和机械性能通过各种先进的方法进行表征。分析结果表明，所得涂层由羟基磷灰石（HAp）和多壁碳纳米管（MWCNT）相组成。与 Ti6Al4V 上的纯 HAp 涂层相比，HAp-MWCNT 复合材料中 MWCNTs 的存在使涂层与基材之间的附着力提高了约 2.3 倍，硬度提高了 20%，而 HAp-MWCNTs/Ti6Al4V 的溶解度降低了约 40% .
