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, MoS.sub.2 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.degree.-800.degree. 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.degree.-800.degree. F. and is stable at such temperatures.

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:
Herein disclosed is a dry type continuous wire drawing process which can retain satisfactory working circumstances while eliminating the problem of disposal of waste liquids. The wire drawing process includes the steps of descaling a wire to be drawn, coating the descaled wire with a lubricant, and drawing the lubricant-coated wire through a drawing die. The descaling step is conducted in a mechanical manner. At the lubricant coating step, the descaled wire is once coated with lime powder and then with metallic soap powder. Thus. the three steps recited are conducted under dry and continuous conditions. At the lubricant coating step, the lime-coated wire may be coated with powder of sodium stearate before it is coated with the metallic soap.
