Examination of Wetting by Liquid Zinc of Steel Sheets Following Various Kinds of Abrasive Blasting

Abstract

Abrasive blasting is one of the methods of surface working before hot-dip zinc-coating. It allows not only to remove products of corrosion from the surface, but it also affects the quality of the zinc coating applied later, thereby affecting wettability of surface being zinc-coated. The surface working can be done with different types of abrasive material.
