    Abstract: The present invention relates to a low-friction member imitating shark skin and a manufacturing method therefor, the low-friction member implementing a structure similar to shark skin and having riblets by stacking, in layers, composite particles formed by attaching spherical particles on the surfaces of plate-shaped particles, and thus the low friction member has excellent low-friction characteristics. The present invention comprises: a base plate; plate-shaped particles stacked in layers on the surface of the base plate in the form of scales; and a plurality of spherical metal lubricating particles having a size smaller than that of the plate-shaped particles, and coated on the surfaces of the plate-shaped particles, wherein the metal lubricating particles are arranged in the form of a bridge connecting the base plate and the plate-shaped particles, and the plate-shaped particles to each other.

    Abstract: A wiresaw cutting fluid composition of the present invention comprises 25 to 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 (M n ) of at least 5 kDa, and is present in the composition at a concentration sufficient to provide a Brookfield viscosity for the composition in the range of 50 to 1000 cP, e.g., 50 to 700 cP, at 25 °C at a spindle rotation rate of 60 rpm. In one embodiment, the viscosity modifier comprises a polymer having a weight average molecular weight (M w ) of at least 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 10 4 s -1 .
