Something about ceramic coating pulley

In the pursuit of a method for the preparation of defect-free ceramic coating pulley fibers, applicants have developed a novel coated fiber, produced by electrophoretic deposition. This ceramic coated fiber is especially suitable for use as a reinforcing element in metal matrix composites.
As used herein, the term "filament" shall refer to a single strand of fibrous material, "fiber tow" shall refer to a multi-filament yarn or array of filaments, a "wire" shall refer in general to metallic filaments or tows, a "fiber core" shall indicate a filament, fiber tow, or wire suitable for coating by the process of this invention, and the term " ceramic coated fiber" or " coated fiber" shall refer to a fiber core of an electrically conductive material, or a material which has been made to be conductive such as by a flash coat of carbon or a metallizing layer, upon which has been deposited a uniform ceramic layer, such that the diameter of the fiber core is greater than the thickness of the applied ceramic. Conversely, for convenience, the term " ceramic fiber" or "fiber" shall refer to an electrically conductive fiber core material upon which has been deposited a uniform ceramic layer, such that the thickness of the ceramic layer exceeds the diameter of the fiber core.

A very detailed introduction of ceramic coating pulley. I'd like to know whether the ceramic coating pulley sometimes used as a kind of chevrolet auto parts?
