摘　　要：介绍了一种钛合金叶片强化抛光原理,该方法将传统的强化与抛光工序合二为一。建立了强化抛光试验装置,对钛合金叶片进行了强化抛光试验。研究了磨块、频率、时间、振幅等对强化抛光的影响。试验表明:强化抛光后,钛合金叶片表面粗糙度从Ra0.35～0.5μm下降到Ra0.1～0.12μm,疲劳强度提高了约50%。The principle of strengthening and polishing titanium alloy was introduced, which combined strengthening and polishing into a single unit. Experimental equipment of strengthening and polishing vibration was established, applied on strengthening and polishing titanium alloy blades. The influence of grinding block, frequency, time, amplitude and so on to strengthening and pohshing was studied. Test shows： the strengthen polishing surface roughness of titanium alloy blades was reduced from Ra0.35 0.5μm to Ra0.1 - 0.12μm, The fatigue strength enhanced approximately 50%.
