Abstract

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.
