    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 work machine, such as a hauler at a mining site, includes a conductor rod housing concentric metal tubes for receiving electrical power from a contactor sliding on a power rail. Electrical connectivity between conductors within the conductor rod are provided using a conductive liquid. Corrosion barriers are used to protect the conductors while maintaining the electrical connectivity between the conductors.

    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.

    Abstract: A method for installing a sensor on a component is provided. The method includes attaching the sensor to a surface of the component. The method includes covering the sensor using a metal wire. The method includes applying a multilayer coating on the metal wire. Applying the multilayer coating includes applying a first coating. The first coating is capable of being machined. Applying the multilayer coating includes machining the first coating and applying a second coating over the first coating. The second coating is a ceramic oxide and the second coating is configured to serve as a thermal and dielectric barrier. Applying the multilayer coating also includes applying a third coating over the second coating. The third coating is configured to provide erosion resistance.

    Abstract: A work machine, such as a hauler at a mining site, includes a conductor rod housing concentric metal tubes for receiving electrical power from a contactor sliding on a power rail. Electrical connectivity between conductors within the conductor rod, between the concentric metal tubes, are provided using a conductive liquid. Corrosion barriers are used to protect the concentric metal tubes from corrosion resulting from contact with the conductive liquid. The corrosion barriers are electroplated and include nickel phosphide and/or cobalt phosphide to maintain the electrical connectivity between the conductors, while protecting the conductors from corrosion.
