    摘要： A wiresaw cutting fluid composition of the present invention comprises about 25 to about 75% by weight of a particulate abrasive suspended in an aqueous carrier containing a polymeric viscosity modifier that comprises a polymer including a majority of non-ionic monomer units (preferably 100 mol % non-ionic monomer units), has a number average molecular weight (Mn) of at least about 5 kDa, and is present in the composition at a concentration sufficient to provide a Brookfield viscosity for the composition in the range of about 50 to about 1000 cP, e.g., 50 to about 700 cP, at about 25° C. at a spindle rotation rate of about 60 rpm. In one embodiment, the viscosity modifier comprises a polymer having a weight average molecular weight (Mw) of at least about 200 kDa. When a viscosity modifier of 200 kDa or greater Mw is utilized, a preferred wiresaw cutting method the cutting fluid is circulated and applied by pumps and nozzles operating at a relatively low shear rate of not more than about 104 s−1.

    摘要： [Technical Problem] An object is to provide a sliding system which can achieve both the reduced friction and the enhanced wear resistance by means of a novel combination of a sliding film and a lubricant oil.[Solution to Problem] The sliding system of the present invention comprises: a pair of sliding members having sliding surfaces that can relatively move while facing each other; and a lubricant oil interposed between the sliding surfaces facing each other. At least one of the sliding surfaces comprises a coating surface of a crystalline chromium carbide film. The lubricant oil contains an oil-soluble molybdenum compound that has a chemical structure of a trinuclear of Mo. When the chromium carbide film as a whole is 100 at %, the chromium carbide film contains 40-75 at % of Cr. The chromium carbide film in contact with the lubricant oil containing a Mo-trinuclear appears to react with the Mo-trinuclear adsorbed during the sliding to generate a layered structural body (boundary film) similar to MoS2 on the surface, thereby developing a considerably low friction property.
