中文摘要

镁合金具有低密度、高比强度等优势，是轻量化应用的优异结构材料。然而，相对于已经大规模工业应用的钢铁、钛合金和铝合金，镁合金铸件易腐蚀、绝对强度低、室温塑性差，成为限制其工业化应用的瓶颈。本文旨在采用超声表面滚压对铸态AZ91镁合金进行表面纳米化处理，以提高其力学性能和耐腐蚀性能。结果表明超声表面滚压在铸态AZ91镁合金表面制备出梯度纳米结构和光滑表面（Ra 0.036 μm）。超声表面滚压使得AZ91铸态镁合金样品的屈服强度和抗拉强度分别提高了55%和50%，表面硬度提高了24%，而断裂延伸率没有显著下降。超声表面滚压的AZ91镁合金样品在3.5wt% NaCl水溶液中具有良好的耐腐蚀性。与未处理样品相比较，浸泡1 h后超声表面滚压处理样品的腐蚀电流密度降低63%，浸泡24 h后腐蚀电流密度降低25%。强度和硬度的提高主要来源于梯度纳米结构，而腐蚀性能的提高主要源于表面纳米结构、光滑表面和残余压应力。

Abstract

Abstract

Mg alloy casting parts commonly suffer from drawbacks of low surface properties, high susceptibility to corrosion, unsatisfactory absolute strength, and poor ductility, which seriously limit their wide application. Here, a surface nanocrystallization technique, i.e., ultrasonic surface rolling (USR), was applied on an as-cast AZ91 Mg alloy sheet to improve its corrosion resistance and mechanical properties. The USR produces double smooth surfaces with Ra 0.036 μm and gradient nanostructured surface layers on the sheet. Due to this special microstructure modification, the USR sheet exhibits 55% and 50% improvements in yield strength and ultimate tensile strength without visibly sacrificed ductility comparable to its untreated counterpart, as well as a 24% improvement in surface hardness. The USR sheet also shows good corrosion resistance in 3.5wt% NaCl aqueous solution. The corrosion current density of the USR sheet reduces by 63% after immersion for 1 h, and 25% after immersion for 24 h compared to that of the untreated counterpart. The enhanced strength and hardness are mainly related to the gradient nanostructure. The improved corrosion resistance is mainly ascribed to the decreased surface roughness, nanostructured surface, and residual compressive stress. The present results state that USR is an effective and attractive method to improve the multiple properties of Mg alloy casting parts, and thus can be used as an additional and last working procedure to achieve high-performance Mg alloy casting parts.
