| 摘 要： | 应用2KW—CO_2激光器,在GH140合金表面进行NiCOCrAlY包覆涂层重熔处理。结果表明,控制恰当激光工艺参数,可使激光重熔区组织细化,成分均匀、涂层致密性、附着力显著提高。从而有效改善了抗蚀性和抗冷热疲劳性,并能保持原涂层良好塑性。

| Abstract: | 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. |
