Abstract
A vacuum deposition process suitable for coating discrete articles with a zinc-rich, fully alloyed layer is described. In a process step of contacting the article with metallic Zn vapor, the temperature of the article is equal to or higher than the dew point of the Zn vapor. The process results in a coating having a uniform thickness, even on less accessible surfaces. Additionally, the roughness of the steel substrate is essentially preserved. By properly engineering the surface of the substrate, coated articles can be obtained having a roughness providing for optimal paint adhesion.
