This work deals with the study, development and characterization of innovative transparent coatings applied onto precious metals and obtained through the Plasma Enhance Chemical Vapor Deposition (PE-CVD) technique. The chemistry of coatings is mainly based on silicon and exygen, based on the formula SiOx. They have already proved to be inert to the corrosion phenomena deriving from the atmosphere and to provide a good resistance to scratches, making them very appealing for jewelry applications. The aim of the paper is to answer one very simple question: Is the process feasible?
