Optimization of Laser Shock Peening For Titanium

Present competitive world is looking for Components with high strength and fatigue resistance finding their applications in aerospace, turbine parts and especially bio-medical devices with high bio-compatibility. Advanced engineering techniques are required to produce parts of higher complexities and desirable surface qualities. Laser peening stood first in a row of all various surface treatments of metallic component. A Fundamental purpose of nobility of the nearby variations in residual stress that happen inside the processed region, that are sensitive to processing variables and not effectively measured tentatively. The rule of residual stress is important in guaranteeing the nobility of engineeringsegments and LaserShock Peening (LSP) process can be utilized to great impact to present the gainful compressive residual stress levels as required. It is, nonetheless, hard to utilize ordinary laser peening rule frameworks to set up the perfect peening state that will bring about the best execution. This paper results from a study to optimize the laser peening parameters for a typical titanium. ND-YAG laser equipment was taken for the experimental work and statistical Taguchi technique was used to bound the number of experiments necessary for optimization to be feasible.
