Abstract In this study, the effects of Cu content on wear, corrosion, and tribocorrosion resistance of Ti-10Mo-xCu alloy were investigated. Results revealed that hardness of Ti-10Mo-xCu alloy increased from 355.1 ± 15.2 HV to 390.8 ± 17.6 HV by increasing Cu content from 0 % to 5 %, much higher than CP Ti (106.6 ± 15.1 HV) and comparable to Ti64 (389.7 ± 13.9 HV). With a higher Cu content, wear and tribocorrosion resistance of Ti-10Mo-xCu alloys were enhanced, and corrosion resistance showed an initial increase with a subsequent decrease. Wear mechanisms under pure mechanical wear and tribocorrosion conditions of Ti-10Mo-xCu alloys were a combination of delamination, abrasion and adhesion wear.

Cu含量对承重骨植入用Ti-Mo-Cu合金腐蚀、磨损和耐摩擦腐蚀的影响

摘要 本研究研究了Cu含量对Ti-10Mo-xCu合金的磨损、腐蚀和耐摩擦腐蚀的影响。结果表明，通过将 Cu 含量从 0 % 增加到 5 %，Ti-10Mo-xCu 合金的硬度从 355.1 ± 15.2 HV 增加到 390.8 ± 17.6 HV，远高于 CP Ti (106.6 ± 15.1 HV) 并且与 Ti64 (389.7) 相当± 13.9 高压）。随着Cu含量的增加，Ti-10Mo-xCu合金的耐磨性和耐摩擦腐蚀性能增强，耐腐蚀性能呈先升高后降低的趋势。Ti-10Mo-xCu合金在纯机械磨损和摩擦腐蚀条件下的磨损机制是分层、磨损和粘附磨损的组合。
