摘要 |
A post plating or post coating method for improving formability and weldability properties in sheet steel product having a protective zinc or zinc alloy layer formed on at least one surface thereof. The steps of the method comprise immersing the sheet steel product into a bath containing at least zinc to apply the protective layer, removing the sheet steel product from the bath, the sheet steel product having a protective zinc or zinc alloy layer formed on at least one surface thereof, and applying an alkaline solution to the protective layer to form a zinc oxide layer thereon, the alkaline solution being applied at a location outside the bath. <IMAGE> |
