Automatic three- plastic of cycles enhanced by a coating anti - wear produced by thermal spraying or cold sprays

摘要

The method involves activating a support surface (2) of a pedal body (1) in a mechanical manner with sanding and shot-blasting, and in a chemical manner by an acid attack. A coating, which is made of ceramic, metallic or cermet material, is obtained by thermal projection or cold spray projection. A layer of cermet, ceramic or metallic material is formed on the surface of the pedal body for protection. The material layer is finished by surfacing, brushing or polishing.
