Patent number: 11885289Abstract: An example component of a machine includes a core layer and an outer layer encasing the core layer. The outer layer has a greater carbon concentration and hardness than the core layer. The outer layer may also be compressively stressed, while the core layer may have tensile stress. The stress and/or hardness profile of the component may enhance its resistance to cracking, particularly in applications where the component is impacted by other object and/or operates at elevated temperatures. The component, such as parts of a fuel injector, may be formed by rough forming the component, carburizing the component, quenching the component, subzero processing the component, and then performing a tempering process. The components may have relatively sharp transition from the high carbon outer layer to the lower carbon core layer. Additionally, the components have a relatively high tempering resistance when used in relatively high temperature environments.Type: GrantFiled: April 30, 2021Date of Patent: January 30, 2024Assignee: Caterpillar Inc.Inventors: Jonathan Robert Crow, Lucy Victoria Berg, Douglas Edward Guyer, II, Michael Alan Pershing
