    摘要： A compressor blade for use in a compressor section of a gas turbine engine, comprising: a martensitic stainless steel compressor blade and an abrasive coating having an anodic component. The compressor blade has a blade portion, a dovetail portion and a platform portion intermediate the blade portion and the dovetail portion, the blade portion terminating in a tip opposite the dovetail portion. A cobalt-based coating overlies at least the blade portion of the compressor blade. The cobalt-based coating comprises a cobalt based material that includes precipitates of tungsten carbide that provide erosion resistance and particles of a sacrificial metal-based material distributed through the cobalt-based coating that provide galvanic corrosion resistance to the system.

    摘要： Embodiments, presented herein are directed to a filtration system including an outer pipe, an inner pipe and a stirrer. The outer pipe is configured to receive a working fluid from a filter inlet. The outer pipe includes a venturi neck and an outer channel. The venturi neck is located downstream of the filter inlet. The outlet channel is located downstream of the venturi neck, wherein the outlet channel is configured to provide an outlet for a first type of impurity. The inner pipe is co-axially positioned with the outer pipe, wherein the inner pipe is configured to receive a second type of impurity. The stirrer is positioned inside the outer pipe, wherein the stirrer rotates with the inner pipe to substantially separate at least the first and the second types of impurities from the working fluid.

    摘要： An appliance for washing objects is disclosed that effectively and energy-efficiently filters oil-based residue from a fluid such as washing fluid that drains from a basin in the appliance. In one illustrative embodiment, an appliance includes a novel filter assembly for filtering oil-based residue out of the washing fluid. The filter assembly includes a filter layer composed of a material that is both oleophilic and hydrophobic. The filter assembly forms part of a fluid distribution system that has different configurations. A first configuration allows for recirculating filtered wash fluid from an outlet of the filter assembly back into the basin of the appliance. A second configuration allows for draining both the washing fluid from the outlet of the filter assembly and the oil-based residue from a bypass zone of the filter assembly to an appliance outlet.
