Abstract
A rotor disc (1) for a disc brake and the like comprises a circular substrate (2) made of a thermally conductive material, and two superposed coating layers (3) and (4) disposed on both outer circular faces of the substrate. The outer coating layer (3) is made from a high thermal conductivity and high wear resistant material such as carbon silicon carbide composite or metallic type material. The inner coating layer (4), is made from a thermally insulating material such as zirconia or other ceramic material. The dimensions of the substrate and layer and the material from which they are made may be tuned for optimum performance. The inner layer (4) operates to protect the substrate from the heat and high temperatures generated at the outer surface of the disc (1) in use.
