A process for the preparation of a metallic surface permits securing a coating to this latter. The process comprises etching on a matrix (11) of hard metal a series of relief designs (12) separated by empty spaces (13). The etching has the effect of creating microcavities (15) in the metal adjacent to the empty spaces (13). The matrix (11) is applied by pressing to a disc of metal softer than that of the matrix (11) to impress the relief designs (12) and the microcavities of the matrix on the disc. The process is particularly useful for the production of a stamped cooking utensil.
