摘要:
Described herein are lubricant compositions that include combinations of lubricant additives that are effective at improving the surface finish of a range of manufactured materials and equipment. In particular, friction modifiers and antiwear additives are employed to decrease surface roughness of additive manufactured (AM), e.g., 3D printed, materials and equipment in concert with maximizing energy efficiency.

Water-based cutting fluids for use with diamond wiresaws that are used for cutting or otherwise treating hard brittle materials, e.g., silicon ingots, comprise: A. Water-soluble, polymeric dispersing agent, typically a polycarboxylate; B. Optionally wetting agent; C. Optionally defoamer; B. Optionally corrosion inhibitor; E. Optionally chelant; F. Optionally biocide; and G. Water. Typically water comprises at least 50 weight percent of the fluid, and the polycarboxylate is grafted with a polyalkylene glycol, e.g., polyethylene glycol.

The present invention provides an anti-seizure agent for hot steel working comprising: an inorganic component as a first component; sodium hydroxide as a second component; water-soluble resins and/or water-soluble surfactants as a third component; and water, wherein, to the mass of the sum of the first component, the second component, and the third component as 100 mass %, the anti-seizure agent contains: 96.5 mass % or more and 99.98 mass % or less of the first component; 0.01 mass % or more and 2. 0 mass % or less of the second component; and 0.01 mass % or more and 1.5 mass % or less of the third component, and the inorganic component is one or more selected from a group consisting of Al 2 O 3 , SiO 2 , CaO, B 2 O 3 , K 2 O, and Na 2 O. This anti-seizure agent for hot steel working exhibits excellent wettability and surface firm-adherability to the steel; moreover, the coating layer formed after application solidly adheres to the steel and does not come off in the environment of both cold and hot working.

摘要:
An additive for lubricant or fuel, comprising at least one member selected from substituted hydroxy aromatic ester derivatives represented by general formulae (I) and (II), (wherein R1 through R5 represent each an organic group having six or more carbon atoms; a, b, d, e, k and m represent each 1 to 3; c, f, g, i and j represent each 0 to 3; h represents 0 to 4, provided f+g=1 to 3 and h+i=1 to 6); a lubricant or fuel additive composition containing the same; and a lubricant or fuel composition containing the same. The additive is suitable as an ashless cleaning agent that is excellent in high-temperature stability and can substitute for metallic cleaning agents. The lubricant or fuel composition containing the same is suitable as an internal-combustion engine lubricant or fuel capable of coping with future severe exhaust gas regulation.
