Effect of Laser Solution-Aging Process Parameters on the Hardness and Water Erosion Resistance of 17-4PH Stainless Steel

Effect of Laser Solution-Aging Process Parameters on the Hardness and Water Erosion Resistance of 17-4PH Stainless Steel

To address the issues of the last-stage blades of steam turbines being susceptible to pitting，water erosion and even fracture，surface laser solution-aging strengthening treatment was carried out on 17-4PH precipitation-hardened stainless steel using a rectangular laser spot with dimensions of 22.0 m...
