Abstract
Abstract ALUMINUM-ZINC COATED FERROUS PRODUCTS WHICH ARE PARTICULARLY RESISTANT TO CORROSIVE FLAKING SUCH AS MAY OCCUR IN EXTREMELY CORROSIVE ENVIRONMENTS ARE PROVIDED BY ACCELERATED COOLING OF THE COATING ON THE PRODUCT AS IT EMERGES FROM A COATING BATH CONTAINING MOLTEM ZINC AND ALUMINUM. THE COOLING IS ACCOMPLISHED AT A MINIMUM RATE OF COOLING WHICH WILL PREVENT LATER CORROSION FLAKING OF THE COATING.
