Abstract: A steel track chain component (162, 164, 166, 168, 202, 204), such as a track bushing (204), may be formed with a carburized portion (404), a hardface portion (412), and a core portion (410). The core portion (410) may be softer than the carburized portion (404), which in turn, may be softer than the hardface portion (412). This configuration of the various portions of the component (162, 164, 166, 168, 202, 204) may allow for relatively high wear resistance of the component (162, 164, 166, 168, 202, 204), as well as toughness. The core portion (410) may be mostly ferrite crystal structure, while the carburized portion (412) and the hardface portion (412) may include martensitic and/or austenitic crystal structure. The carburized portion (412) may be formed by carburizing the track chain component (162, 164, 166, 168, 202, 204) in a heated and carbon rich environment. The hardface portion (412) may be formed by welding a hardface alloy over at least a portion of the carburized portion (404).
