Application of Laser Processing Technologies on Turbine Blades
With different laser processing technologies such as laser alloying, laser repairing and laser solid solution strengthening, two kinds of steam turbine blades with 2Cr13 and 17-4PH are hardened and repaired. Before and after hardening or remanufacturing, the microstructures, microhardness, residual stress, wear resistance, anti-corrosion and anti-cavitations properties are measured. The results confirm that laser processing technologies could be applied to strengthen and repair turbine blades.
