Abstract:
A cooking vessel includes a vessel body having a partially coated, textured stainless steel inner surface having a plurality of ribs rising above recesses having bottoms covered with a non-stick coating. The ribs have uncoated tops and sides that are separate from the bottoms of the cavities. The sides connect the tops to the bottoms. The tops rise above the non-stick coating covering the bottoms. According to the invention, the non-stick coating rises over the sides from the bottoms towards the tops without exceeding the height of the tops, and the bottoms and the sides have a rough surface under the non-stick coating. Also included is a method for producing a cooking vessel.
Abstract:
Provided is a method of producing a cooking vessel, including the following steps: forming a blank from a sheet of stainless steel; drawing of the blank to form a cap comprising an interior surface and an exterior surface, the interior surface comprising a flat base area surrounded by a side wall; hot stamping of a diffuser base onto the exterior surface of the cap; engraving of a grid pattern over at least one portion of the base area of the interior surface of the cap to form a network of ribs having top surfaces that extend above the valleys and side surfaces that are distinct from the bottom surfaces of the valleys, said side surfaces of the ribs connecting the top surfaces of the ribs to the bottom surfaces of the valleys, the side surfaces of the ribs forming ramps connecting the top surfaces of the ribs to the bottom surfaces of the valley; sanding of at least the engraved base area of the interior surface of the cap, to create roughness; applying a non-stick coating on at least the sanded, engraved base area; and brushing and/or polishing of at least the sanded, engraved and coated base area to reveal the stainless steel on the top surfaces of the ribs.
Abstract:
The present invention relates to a method for obtaining an item of cookware, comprising the following steps of: producing or providing a blank from a textured sheet of stainless steel having at least one textured face, stamping the blank in order to form a cap (2) having an inner face (3) and an outer face (4), the outer face (4) having parts in relief corresponding to the textured face of the blank, optionally, partially covering the outer face (4) of the cap (2), carrying out a mechanical finishing treatment of the free surface of the outer face (4) of the cap (2) in order to expose the stainless steel at the parts in relief of the free surface of the outer face (4) of the cap (2). The present invention also relates to an item of cookware comprising a stamped cap (2) made of stainless steel having an inner face (3) and an outer face (4), wherein the outer face (4) of the cap (2) has a textured free surface (5).
Abstract:
Provided is a food cooking surface for a cookware item or an electrical household cooking appliance, consisting of a deposit of nitride of metal elements on a substrate, the metal elements of the deposit comprising one or more X transition metal(s) and aluminium. The production of the deposit comprises a nitridation step in arder to obtain a coating of type (X,Al)N. According to the invention, the (X,Al)N-type coating is a coating of nitride(s) of the one or more X transition metal(s), enriched with aluminium, in which niobium and/or zirconium is/are make up the most part of the X transition metal(s), the atomic ratio of aluminium in the metal elements of the deposit being at least equal to 20%. Also provided are cookware items and electrical household appliances intended for the cooking of food, comprising the above-mentioned type of cooking surface.
Abstract:
Provided is a multilayer cutting blade (1) including a core (2) that has a cutting wire (3), two side flanks (5), and two intermediate connecting thicknesses (4), the side flanks (5) being made of a corrosion-resistant tough metal alloy, each intermediate connecting thickness (4) having a first face (8) for connecting to the core (2) and a second face (9) for connecting to one or the other of the side flanks (5), the first connecting face (8) and the second connecting face (9) being made of copper or a copper alloy. The core (2) is made of martensitic stainless steel, and the thickness of the core (2) is greater than or equal to one third of the thickness of the cutting blade (1), and preferably greater than or equal to half the thickness of the cutting blade (1).
