Abstract
An anti-oxidation coating, particularly for the exposed peripheral regions of graphite brake discs for aircraft, comprises a layer of silicon on the surface of the graphite, a layer of nickel overlying the silicon layer and a layer of chromium overlying the nickel layer. The silicon layer is suitably formed by flame-spraying followed by arc-melting, and the nickel and chromium layers by electroplating.
