As a critical material for high-end equipment parts like aero-engines

titanium alloy has good high specific strength

excellent corrosion resistance and super fracture toughness and fatigue performance. As a typical aerospace difficult-to-machine material

the surface integrity of the titanium alloy during the manufacturing process has a crucial impact on its service performance and reliability. On this basis

the research advances on the current research of surface integrity in the titanium alloy manufacturing process are reviewed from the four technological perspectives of cutting

grinding

composite processing and non-traditional machining. Finally

the prospect of future research on cutting

grinding

composite processing and non-traditional machining technology of titanium alloy are prospected.
