METHOD OF OBTAINING A COOKING VESSEL WITH A HEAT-DIFFUSING BOTTOM AND CULINARY ARTICLE OR ELECTRICAL COOKING APPARATUS COMPRISING SUCH A COOKING VESSEL

摘要

The present invention relates to a method of manufacturing a cooking vessel, comprising the steps of: - fabricating a bowl (10) by molding a substrate (16) made of ordinary steel; - softening and oxidizing the bowl To form a nitrided intermediate layer (17) coated with an oxidized surface layer (18) on the substrate (16), - performing mechanical wear of the oxidized surface layer (18) on the outer surface of the vessel (10) (The outer surface includes at least a portion of the bottom 11 of the vessel 10), and assembling the heat spreading element 20 made of aluminum on the outer surface by heat stamping. The present invention also relates to a cooking utensil or a cooking appliance including the cooking utensil produced by the above method.
