▎ 摘　　要

NOVELTY - Article comprises a base and a coating is applied on the surface. The coating includes a corrosion resistant layer and onto which an external layer is applied which has conductive characteristics. The external layer is formed as a non-continuous layer in the form of discrete areas. USE - Article used as bipolar plate for a fuel cell coated with a coating (claimed). ADVANTAGE - The article has excellent conductivity, and eliminates the formation of pinholes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for forming a coating on the surface of an article, which involves: (A) depositing a corrosion resistant layer includes a metal or alloy and/ or an oxide or nitride of a metal or alloy selected from titanium, zirconium, niobium, hafnium or a carbon material using appropriate targets of the selected materials which are sputter deposited from magnetrons into a chamber in which the the articles are located and moved, either linearly or rotatably; and (B) applying an electrically conductive external layer to the the corrosion resistant layer and where applying the external layer to form a non-continuous layer so as to allow portions of the corrosion resistant layer to be exposed at the external surface of the coating of the article.
