Abstract:
A wire rod is payed out from a pay-off stand and 1 descaled in a descaling process. After preheating to a predetermined temperature by a preheating device, it is subjected to a lubrication pretreatment through a zinc calcium phosphate solution applied with ultrasonic wave in the lubrication pretreatment process. After rinsing process, the lubrication-pretreated wire rod is coated with a calcium stearate or a sodium stearate in lubricating process. Thereafter, the wire rod is dried sufficiently in drying process, and then added with a predies lubricant in wire drawing process and coiled by a coiler.
Abstract:
Disclosed is a lubricating oil which has a low viscosity and a low vapor pressure at the same time, is free from a risk of inflammation and excellent in heat resistance. The lubricating oil has friction characteristics equivalent to those of the conventional hydrocarbon lubricating oils, and can be used for a long time under extremely severe conditions such as at high temperatures in vacuum condition. The lubricating oil contains, as a base oil, an ionic liquid which is composed of cations and anions and has an ion concentration of not less than 1 mol/dm3.
Abstract:
A threaded joint for steel pipes comprising a pin and a box each having a contact surface including a threaded portion and an unthreaded metal contact portion, characterized in that the contact surface of at least one of the pin and the box has a solid lubricant coating formed thereon which comprises a lubricating powder, ultraviolet screening fine particles, and a resin, wherein the ultraviolet fine particles are fine particles of one or more substances selected from titanium oxide, zinc oxide, and iron oxide.
Abstract:
A protective agent for an image bearing member of an image forming apparatus. The protective agent is applied onto a surface of the image bearing member and includes a hydrophobic organic compound (A), an inorganic fine particle (B), and an inorganic lubricant (C).
Abstract:
An aqueous lubricant for use in plastic working of a metallic material which comprises (A) a water soluble inorganic salt and (B) a wax, wherein the components are dissolved or dispersed in water, and wherein a solid concentration ratio (weight ratio) (B)/(A) is 0. 3 SIMILAR 1.5. and a method for producing a lubricative film, characterized in that a lubricative film is produced by applying the aqueous lubricant, preferably in a dried weight of 0.5 SIMILAR 40g/m , on the surface of a metallic material, providing no chemical conversion layer thereon, followed by drying. The aqueous lubricant preferably further comprises (C) a metal salt of a fatty acid in a solid concentration ratio (C) /(A) of 0.01 SIMILAR 0.4. The water soluble inorganic salt (A) is preferably selected from among a sulfate, a silicate, a borate, a molybdate and a tungstate. The wax is preferably a synthetic wax which is dispersed in water and has a melting point of 70 SIMILAR 150 DEG C. The metal salt of a fatty acid (C) is preferably obtained through reacting a saturated fatty acid having 12 SIMILAR 26 carbon atoms with a metal selected from among zinc, calcium, barium, aluminium, magnesium and lithium. The aqueous lubricant can be used for imparting excellent lubricity with ease to the surface of metal having no chemical conversion layer formed thereon.
Abstract:
A lubricant coating disposed between a substrate and a counter surface comprises a reaction layer immediately adjacent the substrate. A bonding layer is immediately adjacent the reaction layer, with the bonding layer comprising a first composition. A low friction, lubricious layer is immediately adjacent the bonding layer, with the lubricious layer comprising a second composition that is different from the first composition.
Abstract:
A solid film lubricant system for protecting metal wear interfaces subject to high temperatures and wet lubrications, comprising an oil-attracting solid lubricant mixture with at least two elements selected from the group of graphite, MoS2 and BN; a support (i.e., hard lands or hard sublayer) for the mixture to loads of at least 10 psi at temperatures of 600 DEG -800 DEG F. while being thermally stable; a thermally stable thermoset polymer matrix adhering the mixture to the support or the wear surface, the polymer having inherent hydrocarbon chemical attraction to form a tenacious oil film of the lubricating oil on the wearing surface. A method of making anti-friction coated surfaces comprising providing a light metal based cylinder surface (i.e., metal base or alloys of aluminum, titanium, or magnesium); exposing nonoxidized metal of the surface; applying a high elastic modulus load-supporting metal layer onto at least portions of the light metal cylinder surface; and simultaneously distributing a solvent-based solid film lubricant mixture and thermoset polymer onto at least portions of the layer at about room temperature to form a coating of desired thickness. An engine block with one or more anti-friction coated cylinder bore surfaces, comprising a hard, load-supporting face on the bore surface; and a coating on the face comprised of an oil-attracting solid lubricant mixture and a thermoset polymer that supports loads of at least 10 psi at temperatures of 600 DEG -800 DEG F. and is stable at such temperatures.
