ABSTRACT:
A metallized article (10) having a non-conductive surface (11) and a plurality of depressions (12) in the surface (11). A first layer of metal (13) being mechanically bonded to the non-conductive surface (11), such that the mechanical bond is enhanced by the interaction of the first layer of metal (13) and the depressions (12). An intermediate layer of metal (14) bonded to the first layer (13). A finish layer of metal (15) being bonded to the intermediate layer (14). The finish layer (15) being a metal which readily accepts a high polish or shine. A process for metallizing such an article having a non-conductive surface including the steps of etching the surface of the article with fluoride containing salts and the depositing of a first layer of metal onto the etched surface. The process further including depositing an intermediate layer of metal in an electroless manner, and then depositing a finish layer of metal by electrolysis.
