Abstract

Procédé de formation d'une couche protectrice calorifuge anti-érosive à la surface intérieure de canons. On ajoute des additifs engendrant les contraintes thermiques à la charge propulsive, ces additifs se déposant sur la surface intérieure à l'état pur ou sous forme de composés chimiques, dans une proportion telle qu'il se forme une couche de faible conductibilité thermique, cohérente, résistante à l'usure, à point de fusion élevé, dont l'épaisseur est déterminée par un état d'équilibre entre l'enlèvement en raison des contraintes thermiques et mécaniques et la reconstitution. Applications aux armes à feu à canon à contraintes thermiques et mécaniques très élevées.A process for forming an anti-erosion heat-insulating protective layer on the inner surface of barrels. Additives generating thermal stresses are added to the propellant charge, these additives being deposited on the inner surface in the pure state or in the form of chemical compounds, in a proportion such that a layer of low thermal conductivity, coherent is formed. , wear resistant, high melting point, the thickness of which is determined by a state of equilibrium between removal due to thermal and mechanical stress and reconstitution. Applications to barrel firearms with very high thermal and mechanical stresses.
