摘要
结合飞机起动机钛合金叶轮的修复需要,研究了Ti-6Al-3.5Mo-1.8Zr-0.23Si(TC11)钛合金激光熔化沉积修复工艺及界面的组织与力学性能。结果表明,激光熔化沉积TC11钛合金及界面重熔区具有典型的魏氏组织特征,基体热影响区组织逐渐由魏氏组织向双态组织过渡;激光熔化沉积TC11钛合金的抗拉强度高于界面过渡区及基体,而塑性稍低于基体。通过采用逐点熔化沉积的方法对叶轮受损叶片进行了修复,经加工检验后通过了超转试验考核,实现了装机应用。
Abstract
To repair the titanium alloy impeller for airplane starter, laser melting deposited Ti-6Al-3.5Mo-1.8Zr-0.23Si(TC11) titanium alloys, as well as the microstructure and properties of the interface, are investigated. The results indicate that the deposited TC11 titanium alloys and the interfacial re-melted layer present a typical Widmansttten structure and the heat affected zone (HAZ) within the substrate changes gradually from Widmansttten to duplex microstructure. Compared to the interface transition zone and the substrate, the as-deposited TC11 alloy possesses higher tensile strength and lower ductility. The damaged impeller blades are repaired by laser melting deposition in a point-by-point way. After machining and checking, the repaired impeller passes the over speed test and comes into real use.
