Abstract
An improved hot dip coating of the zinc aluminum type contains germanium (Ge). In Zn-10Al coatings the addition of 0.1-1.2 Ge weight percent increases the fluidity of the molten metal in the bath and thereby enables substantially thinner coatings having more refined phase structure. Silicon (Si) is found to exhibit an analogous effect, but it not as powerful as Ge. Improved coatings contain zinc, 7-17Al, and 0.1-3(Ge+Si), where Ge ranges from 0-1.2, all weight percent.
