Abstract: An example hydraulic system component of a machine includes a protective coating deposited by high velocity air fuel (HVAF) thermal spray, exhibiting high adhesion strengths and surface morphologies that promote lubricant adhesion and reduce the leakage of oil and/or hydraulic fluid from the hydraulic system. The coating may have surface roughness with Rz values less than 2 μm and hardness of 1000 Vickers or greater. The HVAF coating may be thinner than conventional coatings with thicknesses less than 100 μm. The HVAF coating may be deposited on a variety of steel components with adhesion strengths greater than those achieved by high velocity oxygen fuel (HVOF). The HVAF coating may be formed without time consuming roughening and/or post-grind operations, resulting in cost savings compared to conventional coatings. The coatings may have operational lifetimes of 1000 hours or more.

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

Abstract: A method for coating a component, the method including the steps of depositing, by a thermal spraying process, simultaneously a first material and a second material on a surface of the component to form a rough coating, wherein the first material is of higher hardness than the second material and removing a layer of the rough coating such that the second material plastically deforms and produces a finished coating having a finished surface with an Rz value of less than 2 μm.

Abstract: A fabrication method is provided for use in making a component. The fabrication method may include generating a laser beam at a first orientation relative to a wear surface of the component to produce a first laser beam spot having a first characteristic, and feeding a cladding material into the first laser beam spot to produce a cladding layer on the wear surface. The fabrication method may also include generating a laser beam at a second orientation relative to the wear surface of the component to produce a second laser beam spot having a second characteristic, and moving the second laser beam spot along the cladding layer to substantially flatten the cladding layer.
