Theory Analysis and Experiment Investigation of Laser Shock Processing on Titanium Alloy Blade

摘要：

The requirement for blade treatment and the principle of laser shock processing (LSP) were introduced at the beginning of this paper. The key theories and technologies for LSP were analyzed, including improving the pressure model and introducing the technique of absorbing wave layer at the back of blade. The nanocrystallation of titanium alloy surface is realized for the first time using the method of laser shocking. Through treating one kind of blade using LSP, the technology parameters were confirmed. The nature frequency, fatigue life and residual stress were measured. The results showed the blade performance was improved obviously, which established the theory and experiment base of laser shock processing on blisk.
