摘要

b method to produce an article of thin sheet coated article of thin sheet coated, methods to improve the appearance surface of an article of thin sheet and to produce an ingot is coated, and ingot of thin sheet coated with d the invention relates to a method for the production of a Article of thin sheet coated with superpiu00e1sticas properties and the resulting article of thin sheet.The method involves producing a coating layer on at least one face of lamination of an ingot core made of a metal which has the properties superplu00e1sticas, preferably by CO casting, to form an ingot is coated, and then coated with the said laminar ingot to produce u W article of thin sheet.The ingot core includes an element that diffuses from the inside of the ingot to a surface temperatures of formation superpiu00e1stica, deteriorating the surface properties of the ingot. The coating layer is provided with an element (dopant) that reacts with the element of the core to reduce the ability of the element to diffuse through the coating layer.
