在２００℃共融的氯化物熔盐中，以ＭｎＣｌ２作为添加剂，电沉积出Ｍｎ含量为１８％～４０％的Ａｌ－Ｍｎ合金镀层。结果表明，当合金镀层中Ｍｎ含量超过３１％时，具有单一的非晶态镀层，单相非晶态镀层的耐蚀性、硬度等性能均优于双相镀层。Ｔｉ和Ｃｅ的加入，促进了Ａｌ－Ｍｎ金属玻璃的形成，使Ｍｎ含量较低的单相非晶体Ａｌ－Ｍｎ合金电沉积成为可能，提高了Ａｌ－Ｍｎ合金镀层的耐蚀性和硬度，使其点蚀电位提高了２００ｍＶ，
The electrodeposition of Al-Mn and Al-Mn-Ti (Ce) alloys on steel substrate were studied at 200t from eutectic chloride molten salt with a controlled addlition of MnC12, TiCl, and &?&. It was sh that the Al-Mn alloy coating with single anmplmus structure can be obtained den Mn content is above 31 % , and the mion resistance, hardness as mll as decorative properties of single-phase anrnphous coatings are superior to the of dual-phase coating. Ccmpared with aluminum, increasing of 350 -450 mV for pitting potential and 470-560 Hv for rniclDhardness were observed in the single anrnphous coatings. Moreover, It is shown that the addition of elements titanium and cerium canirnprmre the formation of metallic glassy structure of Al-Mn in the coating and can make the mrphous Al-k phase to fom easily in lw IVfncontent. The addition of element Ce or Ti canenhance the amc&m resistance and hardness, i. e. raise the pitting potential for 100-200 mV, the hardness of the coatings canbe increased up to 800 Hv.
