| 英文摘要 | The invention relates to a method for inlet edge hardening of LP stage high rating steam turbine blades in a temperature controlled high power diode laser hardening process, comprising : controlling laser power/scan speed to produce droplet erosion resistant hard layer by laser hardening at a temperature in the range of 1400-1700°C and scan speed of 5-2.00 mm to achieve hardness of about 540 HV up to a depth of about 4 mm. |
