A non-conductive substrate such as glass, alumina, other ceramics, organic plastics such as "MYLAR" (Trade Mark) is first coated with a mixture of Cu and Al by vapour deposition prior to the electrodeposition of a coating of Cu. The substrate is preferably heated to 200 DEG - 400 DEG C. prior to vapour deposition and the Cu-Al mixture contains 95 - 20% Cu and 5 - 80% Al. The aluminium bronze coating formed has a thickness of 500 - 50,000 </>rA. An electrodeposited coating of Ni-Fe may be formed on the Cu coating. |
