AFTER-TREATMENT METHOD FOR TREATING AN ALUMINIUM DEPOSITION OF

摘要

The aftertreatment of aluminium-deposited steel plate is conducted by heat treating the plated steel plate at 450-550 deg.C for less than 2 mins, and bathing it in the distilled water at the temperature higher than 80 deg.C for more than 10 mins. The method is much simpler than the conventional chromate process. Aluminium-plated steel plate treated by this method has an excellent anti-corrosion property and can be used for outdoor structural material.
