    摘要： Engineered surface treatments are applied to different types of hydraulic motors and pumps to improve the life of the contacting surfaces in said motors and pumps. The engineered surface treatments are selected from texture modifications and tribiological coatings and selectively applied to one or both of the contacting surfaces to reduce friction and improve fatigue life under poor lubrication operating conditions.

    摘要： A pump apparatus of simple construction has a bearing structure for which a lubricant is unnecessary. A flow passage for a refrigerant (liquid ammonia) is formed in a housing to provide communication between a suction port and a discharge port, and slide bearing members formed of amorphous carbon are provided in the housing to be fitted into the flow passage to support a rotating shaft. A drive for rotating the rotating shaft is constituted by a rotor, which is fitted into the flow passage and provided with the rotating shaft, and a stator, which is provided outside the housing to surround the rotor, and a pump body is provided midway the flow passage and connected to the rotating shaft to pump a fluid.

    摘要： An inside surface of an internal combustion engine jacket is treated to have a surface roughness Ra smaller than 0.06 μm, and then receives a DLC coating. A method of producing the internal combustion engine jacket includes: forming the jacket from a metal material, polishing an inside surface of the jacket to obtain a polished inside surface of roughness Ra smaller than 0.06 μm, and applying the DLC coating to the polished inside surface.

    摘要： A method for coating surfaces of a screw machine. The method includes the steps of providing at least one of a plurality of screw machine components including a rotor housing having at least a pair of parallel, overlapping bores; at least a conjugate pair of intermeshing rotors located in the bores, wherein each of the rotors has helical lobes having radially outward tip portions and intervening radially inward root portions; rough coating a surface of at least one of the plurality of components with a conformable coating, wherein the coating is substantially unevenly applied to the surface and has variable thickness over said surface; and leveling the conformable coating to a substantially uniform thickness prior to final assembly of the plurality of components, the substantially uniform thickness selected to ease assembly of the components, while maintaining coating performance criteria.
