Anti-corrosion of aluminum alloy refers to the anti-corrosion of ship hull, which is essentially related to the service life of the ship. The corrosion resistance of ship hull depends on the corrosion resistance of raw materials and the anti-corrosion technical measures of repairing ship hull, especially the latter. Cladding protective layer In the mid-1960s, the […]
