Abstract: A torque-transfer component has splines configured for engaging a corresponding feature of another component, at least a portion of each spline being hardened before a friction-reducing surface coating is applied to the splines. The splines are preferably hardened by nitriding, carburizing, induction hardening, or laser hardening, and the friction-reducing coating preferably comprises diamond-like carbon or tungsten carbide. The coating can be applied using, for example, physical vapor deposition, chemical vapor deposition, chemically assisted physical vapor deposition, autocatalytic electroless deposition, electroplating, or an oxygen fuel gun.
