Abstract
A communication device comprising a coated surface having a fine grained coating, the coating including a high nickel content to provide magnetic shielding. The present coating process can be applied to a variety of components and surfaces to provide magnetic shielding in a communications device. Such devices, include, but are not limited to cell phones, hearing aids, and other hearing assistance devices.
Claims12
A communication device including a component comprising a coated surface having a fine grained coating having an average grain size less than 1000 nm, the coating including a mu-metal having a high nickel content to provide magnetic shielding, wherein the fine grained coating is layered on the component using a plasma process without annealing.
