Abstract

La présente invention concerne un procédé de revêtement de la surface d'un article de vaisselle par plasma sous vide, comprenant : une étape de formation de couche de revêtement consistant à former une couche de revêtement en exécutant un traitement par plasma sous vide sur la surface de l'article de vaisselle ; et une étape de traitement thermique consistant à chauffer l'article de vaisselle ayant traversé l'étape de formation de couche de revêtement. Lesdites étapes conférent des propriétés antimicrobiennes, hydrofuges et anti-empreintes à la surface de l'article de vaisselle et la brillance de l'article de vaisselle est améliorée du fait de l'indice de réfraction élevé de la couche de revêtement sans pour autant modifier la couleur unique de l'article de vaisselle.
