Development of Anti-Fatigue Surface Modification Technology of Aeronautical Titanium Alloy
The latest research progress of surface modification technology for improving the fatigue properties of titanium alloys is introduced. This paper sums up the processing ability and mechanism of different processing methods for titanium alloy
such as shot peening
laser shock peening
extrusion or expansion
rolling or roller burnishing
ion implantation and barrel finishing. The residual stress level and fatigue performance of the machined parts are described.
