摘要:

    鎂合金以質(zhì)輕、結構性能優(yōu)異、以及易于回收等眾多優(yōu)點成為裝備制造業(yè)輕量化發(fā)展的首選材料；而且，無論在儲量、特性、應用范圍、循環(huán)利用、以及節(jié)能環(huán)保等方面和鋼鐵相比，均具有非常明顯的優(yōu)勢。首先介紹了鎂合金在近代工業(yè)發(fā)展中的作用以及現(xiàn)實應用存在的主要問題，然后對鎂合金的腐蝕機理、各種因素對鎂合金腐蝕性能的影響以及新型稀土鎂合金的電化學腐蝕行為進行了綜述。最后簡要介紹了幾種比較有發(fā)展前景的鎂合金表面防護技術，并概述了鎂合金腐蝕與防護研究未來的發(fā)展方向。��

Abstract:

    Being light and easy of recycling, magnesium alloys have become the preferred materials for lightweighting in equipment manufacturing industry owing to their excellent structural performance and many other advantages; and compared to steel, magnesium alloys have distinct advantages in terms of reserves, properties, application recycling, energy saving, and environmental protection. Firstly, the role of magnesium alloys in modern industry development and major problems appeared in practical application of magnesium alloys were introduced, and then the corrosion mechanism of magnesium alloy, effects of various factors on the corrosion behavior of magnesium alloys, and the electrochemistry corrosion mechanism of novel rare earth magnesium alloy were summarized. Finally, several prospective surface treatment technologies of magnesium alloys were briefed, and the future development trends of magnesium�餾 corrosion and protection were put forward.
