Abstract
A method of treating a metal layer present as a coating on a sheet metal substrate, wherein a powder is applied to said metal coating by propulsive means (e.g., spraying or the like) when said coating is at least partially in the liquid state. The powder is prepared by atomization in a manner adapted such that the powder is in the form of agglomerates having a mean diameter which is greater than the thickness of said liquid-state metal coating. With this use of this powder, it is easier to treat metal coatings in the liquid state, and the resulting treated coating is highly homogeneous, even if the atomized powder has a plurality of types of components.
