ABSTRACT An article of manufacture, for example a conductor for an electrical wire or cable, is provided with refractory coating 2 preferably formed from a re- fractory metal or semi-metal oxide or nitride and preferably deposited on the surface of the article by a vacuum deposition process such as a sputter ion plating method. Adhesion of the refractory coating, especially At high temperatures may be improved, and migration of the substrate metal 1 through the coating 2 may be suppressed, by varying the stoichiometry of the coating through its thickness and/or by the provision of a metallic or refractory intermediate layer. The articles are particularly suitable for use in circuit and signal integrity cables.
