Abstract

The invention is directed to a coated smoothing iron soleplate which is preferably composed of an aluminum alloy, its anticorrosive coating which is preferably a nickel hard alloy having an extremely scratch-resistant surface capable of sliding well and easy to clean. The coating is preferably applied by a high-speed flame spraying method, followed preferably by a grinding and polishing operation using a drag grinding method.
