Embodiment Construction
[0015] Below in conjunction with specific embodiment, technical content of the present invention is elaborated:
[0016] A coating thermal spraying process for gas turbine turbine blades. For the GE MS6001B gas turbine turbine part of the first stage blades, the blades are sprayed with supersonic spraying method to ensure that the thickness error of the coating can be controlled. Within 50 microns, including the following process steps:
[0017] a. Surface pretreatment: first heat the blades to degrease, place the blades in a heating device, heat the temperature of the heating device to 330-370 ° C, keep at this temperature for one hour, then take out the blades and cool them to 16 -30°C, then carry out surface roughening treatment, place the cooled blades in the sandblasting box, perform sandblasting on the area to be sprayed to roughen the surface of the rotor blades, and put the sandblasting gun in the sandblasting box with the blades The sandblasting area forms an include...
