SURFACE TREATMENT AND ELECTRODEPOSITION COATING METHOD OF LARGE AREA MAGNESIUM ALLOY

摘要

The present invention provides a surface treatment method and an electrodeposition coating method of a large area magnesium alloy, in which wear resistance and corrosion resistance are all excellent, and etching of a surface roughness is reduced in chemical treatment such that coating adhesiveness is improved, environment pollution is reduced, and an operation environment is improved. The surface treatment method of a large area magnesium alloy comprises: a pretreatment step of a large area magnesium alloy including sanding, acid-degreasing, etching, and neutralization processes; and a chemical treatment step of immersing the magnesium alloy into a chemical treatment liquid for the large area magnesium alloy.;COPYRIGHT KIPO 2018
