ABSTRACT:
An electronics enclosure includes an assembly of wall elements having metallic surfaces with a standard oxidization potential within the range of -0.25 to +0.5 volts, the wall elements rigidly secured together, and having a coating of molybdenum phosphate covering the metallic surfaces of the wall elements and providing electrical discharge continuity around the enclosure. The molybdenum phosphate coating provides a required degree of electrical conductivity for adequate electrostatic discharge thereby providing a Faraday cage to filter out any electromagnetic radiation attempting to pass through the enclosure. Of particular importance in the structure is the feature that the molybdenum phosphate is particularly effective as an electromagnetic interference element at junctures between wall elements of the enclosure. The molybdenum phosphate coating may be applied to the wall elements either prior to assembly or following assembly. Preferably, the coating is applied to assembled wall elements with the molybdenum phosphate bridging between adjacent wall elements and bridging across gaps between the adjacent wall elements.
