WPC GEAR TREATMENT
WPC is a permanent surface treatment that reduces friction while strengthening the part. Its unique micro-dimple formation pattern greatly reduces friction and is unmatched by conventional methods of surface treatment. It is a proven process that has been utilized for many years in the racing and automotive industry. WPC can strengthen parts in two ways. First it adds an extremely high level of compressive stress at, and near, the surface. The second, is that the WPC treatment creates a Nano - Crystalline structure at the surface of the metal. Both of these mean that metal fatigue and crack initiation are both noticeably reduced; thus strengthening the gear and shaft.
