Metal mesh and production thereof.

摘要

In the production of an open valve metal mesh comprising a plurality of interconnected strands a part only of which are coated with an electrocatalytically-active material, a coating of a valve metal oxide is formed on those parts of the surfaces of the strands of the mesh which do not have a coating of an electrocatalytically-active material. The mesh may be formed by slitting and stretching a sheet of valve metal which has been coated with an electrocatalytically-active material, the valve metal oxide coating being formed on those surfaces, eg those exposed by the slitting step, which do not have a coating of an electrocatalytically-active material.
