摘要:

鋁鎂合金因其優(yōu)異的耐蝕性、裝飾性、抗氧化性和可加工性成為理想的構(gòu)件防護材料，因其質(zhì)量輕，理論儲氫量高，作為儲氫材料具有廣泛應(yīng)用前景。為使鋁鎂合金得到良好的應(yīng)用，需要制備超細結(jié)構(gòu)純凈合金，電沉積是制備高純合金的有效方法之一。室溫電沉積是在室溫條件下，通過控制沉積參數(shù)實現(xiàn)對合金微觀組織結(jié)構(gòu)和成分的控制，制備高純超細合金。本文綜述了室溫電沉積制備鋁鎂合金的體系和電流密度、沉積方式、鎂離子引入方式及實驗環(huán)境和條件等對鋁鎂合金組成、形貌和晶體結(jié)構(gòu)等的影響，重點介紹了室溫電沉積鋁鎂合金的影響因素及鋁鎂合金在裝飾、防腐蝕和儲氫等方面的應(yīng)用，提出了室溫電沉積制備高純鋁鎂合金存在的問題及未來的發(fā)展趨勢。

Abstract:

Al-Mg alloy is resistant to corrosion and oxide, and moreover, has decorativeness and machinability. All these make it an ideal material to protect. Due to light weight and high hydrogen storage, it has shown good perspective of application as a hydrogen storage material. To obtain good Al-Mg alloy, pure alloys of ultrafine structure need to be prepared. When preparing the alloys which are highly pure, electrodeposition is one of effective ways. At room temperature, the microstructures and components of alloys can be controlled by adjusting deposition parameters, which will lead to preparation of the alloys that is highly pure and ultrafine. In this paper, the effect of some factors on composition of Al-Mg alloy, morphology, and crystalline structure will be reviewed, such as electrolyte composition, current density, deposition methods, ways by which Mg ion is used, and experimental environment and conditions. Especially, the factors are mainly introduced when Mg-Al alloy is prepared at room temperature as well as application of Mg-Al alloy in decoration, resistant to corrosion, and hydrogen storage. Finally, the problems and future trends are presented when Mg-Al alloy is prepared at room temperature.
