PREPARATION OF STEEL SURFACES FOR SINGLE-DIP ALUMINIUM-RICH ZINC GALVANISING |
摘要 |
A process is disclosed for the preparation of a steel surface for single-dip aluminium-rich zinc galvanizing. The process steps comprise: cleaning the surface so as to obtain less than 0.6 mug/cm<SUP>2 </SUP>residual dirt; pickling the surface; applying a protective layer to the surface by immersion in a flux solution comprising bismuth.
