| 摘 要： | 在真空条件下对AZ91HP镁合金进行了激光熔凝处理。研究结果表明,镁合金激光熔凝层均是由α3/Mg和β-Mg17Al12相所构成,且随激光扫描速度的增加,β-Mg17Al12相的相对含量降低。随着激光扫描速度的增加,由于熔凝层组织细化,致使其硬度、耐磨性、减磨性和耐蚀性增加,但因熔凝层中β-Mg17Al12相的相对含量较高,使得激光熔凝层的耐蚀性较镁合金为低。

| Abstract: | AZ91HP magnesium alloys were treated by vacuum laser melting. The result shows that laser melting layers treated by different scaning speed mainly consist of α–Mg andβ-Mg17Al12 phases, and the relative content of β-Mg17Al12 phase decreases with the increase of scaning speed. Because of the refined structure of the melted layer, hardness, wear resistance, antifriction, erosion resistance of the laser melting layer increase with the increase of scaning speed. Compared with magnesium alloy, erosion resistance of the laser melting layer decreases due to high content of β-Mg17Al12 phase. |
