Components, such as gears and other power transmission components, are formed by near-net-forging a high strength, high toughness ferrous metal alloy, surface processing metal alloy to form a hardened surface region (28), and coating the surface region with a lubricious coating (84) as shown in Figure 9.
La présente invention concerne des éléments, tels que des pignons et d'autres éléments de transmission qui sont fabriqués par un forgeage presque à la cote de haute résistance, des alliages métalliques ferreux de dureté élevée, un alliage métallique à traitement de surface destiné à former une région de surface durcie et un recouvrement de région de surface avec un recouvrement lubrifiant.
