The method comprises treating, in a non-reactive gas plasma, one or more nitrided metal elements, applying an adhesive composition suitable for bonding vulcanizable natural and synthetic rubbers to metals on at least a portion of the compound. the nitrided metal surface (s) treated with plasma, contacting the part (s) coated with adhesives of such substrates, and the assembly obtained is then subjected to conditions of heat and pressure for a period sufficient to obtain vulcanizing the rubber composition and curing the adhesive composition. A reservoir 1 of a non-reactive gas (argon) is provided, equipped with a pipe 11 to direct this gas to the reactor 2. A flowmeter 3 is provided to measure the gas flow rates and a pressure gauge 4 is provided in the pipe. 12 to monitor the pressure in the reactor. Valves 21, 22, 23 are provided on the conduits 11 and 12. |
