Abstract:
In one aspect the invention is a carrier-free pulverulent metalworking lubricant containing a resin having a highly polar functional group, and in another aspect is a method of the invention of forging a workpiece in a die which includes the step of applying to at least one of the die and the workpiece a coating of an effective amount of the carrier-free pulverulent lubricant composition. The use of the composition and method of the invention significantly reduces smoke and oily waste generation in hot forging operations by eliminating the use of oils or volatile organic compounds as carriers, while providing acceptable performance, cleanability, and sprayability.
Abstract:
A novel lubrication blend useful per se as a lubricant or as an additive to form a novel lubricant composition. The lubrication blend consists essentially of a mixture of: (1) at least one complex sulfide of antimony, represented by the formula: Sb x S y wherein, x is a number in the range from about 1.7 to about 2.3, and y is a number in the range from about 3.6 to about 4.4, (2) at least one antimony oxide, and (3) at least one lamellar crystalline solid lubricant.
Abstract:
The present invention relates to a cooling fluid for metal cutting, drilling, grinding and other fabricating operations comprising a compound of the formula C₆H₄(OH)COOR, where R is selected from the group consisting of -H,-CH₃,-C₂H₅,-C₃H₇, and -C₄H₉, a ketone with a boiling point of at least about 150°F, and an at least partially soluble acid. The present invention also relates to a process and fluid product made by a certain process for cooling tools and workpieces for metal cutting, drilling, grinding and other fabricating operations comprising the steps of mixing a compound of the formula C₆H₄(OH)COOR, where R is selected from the group consisting of -H,-CH₃,-C₂H₅,-C₃H₇, and -C₄H₉, a ketone with a boiling point of at least about 150°F, and an at least partially soluble acid, the mixture being a cooling fluid, maintaining substantial contact between the cooling fluid and an amount of transition metal or alloy containing at least one transition metal, sufficient to catalyze a reaction within the fluids during fabrication, and operating a tool while maintaining substantial contact between the tool and the fluid during fabrication.

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, usually at about 1000to 1200°C., cooling the melt to within the range about 550°C. to about 970°c., inducing acicular crystal formation, and recovering the acicular crystals. The diameters of the resultant acicular, crystalline calcium metaphosphates can vary from an average of 0.5 micron or smaller up to several microns. Cryst- afs having a length of several centimeters can be prepared. Such acicular, crystalline calcium metaphosphates are useful in a number of applications, and particularly to prepare composites with organic polymeric materials.
