利用２ｋＷＣＯ２激光器对不同合Ｓｉ量的ＡＩ－Ｓｉ合金进行了搭接扫描熔凝处理，通过ＳＥＭ和ＴＥＭ对激光熔凝处理后Ａｌ－Ｓｉ合金的组织结构进行了观察，通过测定在不同介质条件下的阳极极化曲线，讨论了激光熔凝处理对ＡＩ－ｓｉ合金耐蚀性的影响。结果表明，激光处理可改善Ａｌ－Ｓｉ合金在１０％Ｈ２ＳＯ４和１０％ＨＮＯ３溶液中的耐蚀性，而对Ａｌ－Ｓｉ合金在１０％ＨＣｌ和５％ＮａＣｌ溶液中的耐蚀性没有明显的促进作用。
Al-Si alloy with different amounts of Si was lapped and fused by 2kWCO2 laser. The microstructure of Al-Si alloy after laser cladding was observed by SEM and TEM. The anodic polarization curves were discussed. The effects of laser fusion treatment on the corrosion resistance of AI-si alloy were discussed. The results show that the laser treatment can improve the corrosion resistance of Al-Si alloy in 10% H2SO4 and 10% HNO3 solution, but not the corrosion resistance of Al-Si alloy in 10% HCl and 5% NaCl solution effect.
