Abstract

Abstract Translated from French Ce canon est caractérisé en ce qu'il est constitué de trois couches superposées sans solutions de continuité, à savoir : une couche interne en un matériau réfractaire; une couche médiane d'un matériau dont la résistance mécanique est supérieure à environ 250 MPa à 900°C et une couche externe en un acier allié. L'invention concerne aussi le procédé de fabrication d'un tel canon. This barrel is characterized in that it consists of three superimposed layers without solutions of continuity, namely: an internal layer made of a refractory material; a middle layer of a material whose mechanical strength is greater than about 250 MPa at 900 ° C and an outer layer of alloy steel. The invention also relates to the method of manufacturing such a gun.
