Rust removal of zinc-magnesium-aluminum photovoltaic bracket

Does mg affect the corrosion resistance of zinc-magnesium-aluminium alloy steel sheets?

Furthermore, the role of Mg in the corrosion resistance of zinc-magnesium-aluminium alloy steel sheets was determined. The research results indicated that in a marine atmospheric environment, zinc-aluminium-magnesium alloy steel has excellent corrosion resistance, and its external coating provides protection to the substrate.

What are the corrosion products of zinc-magnesium-aluminium alloy steel?

In a marine atmospheric environment, the corrosion products of zinc-magnesium-aluminium alloy steel mainly include Al2 O 3, AlOOH, zinc hydroxychloride (Zn 5 (OH) 8 Cl 2 ·H 2 O), layered bimetallic hydroxides (Mg 6 Al 2 (OH) 16 CO 3 ·4H 2 O), ZnO, and MgCO 3 ·H 2 O.

Does zinc aluminium-magnesium-coated steel corrode in a polluted marine environment?

The corrosion behaviour of zinc–aluminium–magnesium-coated steel in a simulated polluted marine atmospheric environment was investigated. Therefore, an indoor ageing acceleration test was carefully designed by simulating a polluted marine environment.

Does aluminium inhibit the formation of Zn-Fe phase during zinc plating?

Some scholars [7, 10, 11] underscored the role of aluminium in inhibiting the formation of Zn–Fe phase during the zinc plating process, thereby augmenting the corrosion resistance of the coating. LeBozec et al. focused on the intricate microstructures resulting from the addition of magnesium and aluminium.

What is zinc-aluminum-magnesium coated steel (Zam)?

Hence, zinc–aluminum–magnesium coated steel (ZAM), which is obtained by adding Al and Mg on GI, is widely applied in automobile, photovoltaic power generation, and construction fields [ , , , , , , ].

Does Zn-Al-Mg-coated steel halt corrosion?

The emergence of elements like MgZn 2 binary eutectic phase contributed to a more compact morphology, further enhancing effectiveness of the coating. Gu et al. made a significant observation that the corrosion products generated by Zn–Al–Mg-coated steel can effectively halt the progression of further corrosion.
