摘要: 对 TC1 1钛合金抗微动磨损及抗微动疲劳的表面强化工艺进行了研究。试验结果表明,渗氮、等离子喷涂 1 2 % Co包 WC及 α-Al2 O3、离子镀 Ti N及 ( Ti+ B) N、离子注入 N+等对TC1 1钛合金的抗微动磨损能力均有所改善。其中,离子镀 Ti N及 ( Ti+ B) N防护效果较好,形成的表面强化层自身强度高且具有一定厚度,与基体结合性好,降低摩擦系数,使材料的抗微动磨损能力有较大的提高

Abstract: The results show that the capability of fretting resistance of TC11 titanium alloys is improved by nitrizing, ion coating, ion implantation and plasma spraying, among which the ion coating has good protective effects. The results also show that the improvement is more obvious when the surface strengthening layer formed has the high strength, suitable thickness, good combination with basic metal and a low friction frictor.

Key words: titanium alloys, surface treament, nit riding, plasma spraying frettin
