강재 표면에 아크 금속 용사된 Al 및 Al-5 % Mg 코팅의 방지 성능
The Corrosion Protection Performance of Al and Al-5%Mg Coatings Deposited on Steel Surface by Arc Thermal Metal Spray
초록
Arc thermal spray process is widely used to protect the steel from corrosion and abrasion. In the present study, two different coatings i.e. Al and Al-5%Mg were used to compare their corrosion resistance performance and the effect of 5% Mg addition in the properties of deposited coating. The SEM results showed the more compact and less porous morphology of Al-5%Mg coating compared to Al. The corrosion resistance performance of both deposited coatings was studied in artificial ocean water with exposure periods and results are compared. The total impedance values of Al-5%Mg at 0.01 Hz exhibited highest with exposure periods might be attributed to the coating and corrosion products nature and morphology compared to Al coating.
