摘要
综述了目前镁、铝合金表面自纳米化制备方法、性能、耐蚀性等方面的研究。材料经表面自纳米化后,表面纳米层有良好的热稳定性,表面硬度明显提高,不同的工艺对耐蚀性影响不同。提出了表面自纳米化技术研究还需解决的问题及趋势。
The present research condition of surface self-nanocrystallization on magnesium and aluminum alloy was summarized, including micrograph, properties, corrosion resistance. After surface self-nanocrystallization, the surface nano-layer has good thermal stability; surface hardness has a significantly improve; there is a different effect on corrosion-resistance when adopted disparate making process. And the problems to he solved of surface self-nanocrystallization technology and trend are proposed.
