| 摘要 |
This invention relates to a method and means for applying one or more coatings on to a substrate. The invention is particularly, but not exclusively, concerned with applying metal or alloy coatings on to metallic substrates in order to improve the formability and corrosion resistance of the substrates. Known coating processes include hot dip galvanizing, tinning and aluminizing, and in particular the method comprises feeding the substrate through a molten composition of a first coating material and subsequently feeding the so coated substrate into a molten composition of a second coating material whereby the coating of the second material is overlaid upon the coating of the first material.
