Abstract

Method of manufacturing mechanical elements, with high resistance to corrosión, especially valves for thermal engines, and armored elements characterized by manufacturing the element of a corrosión resistant alloy and subjecting, at least the area of said element intended to be in contact with a seat, a shake that reduces the granulometry and hardens the structure.
