Abstract:
A method for treating the phosphate sludge waste from phosphate conversion baths used in the metal forming and metal working industry is described whereby the phosphate sludge is completely converted into a lubricant additive which can be used in lubricant formulations for the metal forming and metal working industry as well as general purpose lubricants. By operation of this process, waste treatment and waste disposal problems associated with the phosphate sludge are essentially eliminated. Various dry-soap lubricant formulations, warm forming lubricant formulations, non-reactive lubricant formulations, and metal precoat formulations containing the recovered or recycled phosphate sludge additive are described. The lime normally contained in many of these lubricant formulations can be significantly reduced or essentially eliminated by using the recovered phosphate sludge additive of this invention, thereby resulting in improved lubricant formulations. The recovered phosphate sludge is especially useful as an Extreme Pressure Additive.
Abstract:
A process for coating a machine part surface wherein the surface is cleaned, abraded and treated so as to render the surface directly bondable to a resin-bonded lubricant coating. A powder coating containing resin and resin-bondable lubricant then is directly applied to the treated machine part surface and cured so as to cross-link the resin.

Abstract:
Lubricating sealants which are resistant to aprotic solvents such as chloroform and carbon disulfide are prepared by forming a grease comprising glycerine, fumed silica, polyethylene glycol and a minor amount of water.
Abstract:
Acicular, crystalline calcium metaphosphate having a length to average diameter ratio of at least 10:1 can be prepared by forming a melt of materials used as a source of calcium, phosphorus and alkali metal, cooling the melt to about 550.degree. C. to about 970.degree. C., inducing acicular crystal formation, and recovering the acicular crystals. The diameters of the resultant acicular, crystalline calcium metaphosphates can average as small as 0.5 micron or smaller. Acicular, crystalline calcium metaphosphate can also be prepared with an average diameter of several microns and a length of several centimeters. Such acicular, crystalline calcium metaphosphates are useful in a number of applications, and particularly to prepare composites with organic polymeric materials.
Abstract:
A method for producing and operating for the first time a transmission unit with a lubricant based on water comprises the following steps: a mixture of vaporizable liquid, a comminuted solid lubricant and a preservative (22) are applied (21) to the finished rotary parts (20) and then dried (23), whereby a coating forms on them. The rotary parts with the coating are fitted into the casing of the transmission unit and the assembled transmission unit is filled with a cooling liquid (25), which is primarily water. The transmission unit is put into operation for the first time (27), the lubricant for further operation only being formed by the abrasion of the rotary parts and distribution of the abraded matter in the cooling liquid. The transmission unit is then operationally ready (28). Furthermore, a lubricant produced by this method is described.
Abstract:
The invention describes an apparatus having an evacuable cavity surrounded by a casing, there being arranged in the cavity and/or on the casing, and projecting into the cavity, at least one friction assembly and/or bearing assembly having at least two elements each having a surface, the two surfaces interacting, and at least one of the two surfaces being coated with a lubricating varnish, at least in the region of their interaction, the varnish comprising a polymeric binder and also molybdenum disulphide (MoS 2 ) and graphite as solid lubricants. The invention further describes an anti-friction paste, an anti-friction dispersion, and the use of a lubricating varnish under high or ultra-high vacuum.
Abstract:
Systems, compositions, methods, etc., that provide significantly enhanced tribological properties to a target substrate such as metal, plastic, wood, glass, etc., by bombarding or showering the target material with bombardment particles substantially saturated with a desirable lubricant composition, typically comprising at least one primary lubricant such as a molybdenum disulphide (MoS2) and at least one polymeric lubricant, such as polytetrafluoroethylene (PTFE), such that the lubricant composition imbeds into the surface of the target material (also called a target substrate).
