  • Method for composing a nano-particle metal treatment composition for creating a ceramic-metal layer
    Patent number: 7867330
    Abstract: The present invention relates to a metal treatment composition including Tin (II) Chloride and processed montmorillonite clay. The addition of Tin (II) Chloride to the composition provides Tin for forming a ceramic-metal layer on the surfaces of the friction pair. Tin (II) Chloride provides Chlorine ions for forming Chloric films for protecting juvenile surfaces which form in the friction zone. The clay is heated and pulverized to produce a powder comprising both particles having crystalline layer structure and salts and oxides. The layered crystalline structure of the clay contains slip planes that transversely shift when tangential pressure from the friction pair is applied thereby lubricating the friction pair. The salts and oxides contribute to the formation of the ceramic-metal layer.

  • Cutting fluid, method for production thereof, and method for cutting ingot
    Patent number: 5693596
    Abstract: A water-soluble cutting fluid is produced by dissolving a polymer fatty acid triglyceride imidazole, 2-methyl-1-stearate, and boric acid imidazole in the dispersion of inorganic bentonite in water thereby preparing a main component and adding oleic acid (agent for enhancing the lubricity), Na salt of ethylenediamine tetraacetic acid (metallic ion adsorbent), benzotriazole (rust-preventing auxiliary agent), and a silicone type defoaming agent to the main component.

  • Rock bit grease composition
    Patent number: 5668092
    Abstract: A rock bit for drilling subterranean formations is lubricated with a grease composition made from a high-viscosity synthetic lubricant basestock and a combination of lubricant additives. The grease composition preferably has in the range of from 1 to 20 percent by weight polyisobutylene, in the range of from 50 to 90 percent by weight ethylene-alphaolefin, up to approximately 40 percent by weight polyalphaolefin, and in the range of from 4 to 45 percent by weight lubricant additives. The rock bit grease composition has a viscosity index in the range of from about 250 to 325, and has an absolute viscosity of greater than about 100,000 centipoise at a temperature of approximately 70.degree. F. and at a shear rate of less than about 40 seconds.sup.-1, without the use of solid metal-containing extreme pressure agents or thickening agents.
