| 中文摘要: |
| 以AZ91D镁合金为基体,Al为合金粉末,采用激光表面改性技术对AZ91D镁合金进行表面改性,详细分析了镁合金改性后的表面组织,并通过盐雾实验对比了改性前后镁合金的耐蚀性,探讨了AZ91D镁合金基体及表面Mg-Al改性层的腐蚀机理,确定最佳激光功率参数为1.5 kW。 |
| 英文摘要: |
| Taking the AZ91D magnesium alloy and aluminum as a substrate and powdered alloy respectively, the surface of AZ91D magnesium alloy was modified by the laser surface modified technology. The modified surface organization was analyzed in detail. The corrosion resistances of alloy before and aftermodification were compared via salt atmosphere experiment, the corrosion mechanism of AZ91D magnesium alloy and Mg-Al modified surface layer were discussed, and determines the optimum parameters of laser power 1.5 kW were determined. |
