Abstract
The invention relates to a method for treating the surface of an electrically conductive object with a refractory metal. In one embodiment, the refractory metal is tantalum and the object is a titanium substrate. The surface layer of mixed tantalum and titanium oxide is produced by first heating the object and tantalum chloride in a reaction chamber and subsequently heat treating the object in an oxygen-containing environment. The electrically conductive object may be, in a non-limiting manner, a DSA solution (Dimensionally stable anodes), a fuel cell or a connector plate.
