METALIZATION METHOD AND PLANT

摘要

Described herein is a method for metalization in high-vacuum conditions for bestowing particular colourings or chromatic effects on the article to be metalized, said method comprising two steps of metalization: sublimation in the vacuum bell in high-vacuum conditions of a first metal; and sublimation in the vacuum bell in high-vacuum conditions of a second metal in the presence of a gas basically constituted by oxygen or ozone. The second metalization bestows upon the article thus treated a particular colouring and/or particular chromatic effects.
