La presente se refiere a un procedimiento de tratamiento en una cámara (3) de una superficie interna (2) de un recipiente (20) de material polimérico para disponer un revestimiento de efecto barrera, que comprende: la introducción del recipiente (20) en la cámara, la introducción en el recipiente (20) de un gas denominado precursor, una vez transformado al estado de plasma, destinado a ser dispuesto al menos en parte sobre la superficie interna del recipiente para formar el revestimiento, El procedimiento también comprende: la transformación al estado de plasma del gas precursor mediante una combinación de excitaciones que comprenden la excitación principal por medio de ondas electromagnéticas de tipo microondas, y una excitación secundaria por medio de una descarga eléctrica de tensión alternada con una frecuencia entre 1 kHz y 15 MHz. La presente también se refiere a un dispositivo que permite implementar el procedimiento de la misma. Method for treating in an enclosure an inner surface of a container made from polymer material, in order to deposit a barrier coating there on, comprises: inserting the container into the enclosure; introducing a precursor gas into the container intended, once transformed into the plasma state, to be deposited at least partially on the inner surface of the container in order to constitute the coating; wherein the method further comprises: transforming the precursor gas into the plasma state by a combination of excitations comprising a main excitation by means of electromagnetic waves comprising microwaves, and a secondary excitation by means of an electrical discharge of alternating voltage having a frequency between 1 kHz and 15 MHz.
