Method of manufacturing a heating article provided with a sol-gel coating

A method of manufacturing an item, notably a culinary item, includes: providing a support in the form of a preform; preparing a sol-gel composition; hydrolyzing the sol-gel precursor, followed by a condensation reaction; applying onto at least one support surface of the preform at least one layer of the sol-gel composition to form a sol-gel coating layer; and thermally treating the sol-gel coating layer to solidify the coating layer. Further, before thermally treating the sol-gel coating, the method includes pre-densifying the coated preform and stamping the preform to produce a final form of the culinary item.

METHOD OF PRODUCING A COOKING VESSEL COMPRISING AN INTERIOR SURFACE OF PARTIALLY COATED STAINLESS STEEL
20190313842 · 2019-10-17 ·

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.
