A Study on Metalliding of Al on Steel from Molten Fluorides
불화물계 용융염중에서 Steel 기지 소재의 Al 전해피복에 관한 연구
Abstract
Diffusion coating(metalliding) of aluminium on steel from molten fluorides(29.2wt.% LiF-11.7wt.% NaF-59.1wt.% KF, FLINAK) was studied. The electrolytic cell consists of a steel cathode and a consumable aluminium anode. Effects of manganese on the aluminium deposition were also investigated. The quality of the deposit was analyzed by SEM, OM, EPMA, EDXA, and also examined by means of Micro-Vickers hardness and corrosion tests. Deposit layer was identified as an aluminium-rich iron alloy caused by diffusion process. The optimum condition for the metalliding was found to be the current density, 50 to
