| 摘 要： | NiCoCrAlY protective coating is remelted on the GH140 alloy surface by 2KWCO2 gas laser,the results of which show that,by controlling proper laser technological parameters, the constitution can be fined,the composition can be well distributed,and the coating compactness and adhesion can be obviously enhanced in the laser-remelting zone. Thus,corrosion resistance and thermal fatigue resistance is effectively improved,and the good plasticity of the original coating is remained.
