The lubricant is contained in the protective base material, and the protective base material is at least in part selectively removable. There is also provided a metal sheet or strip capable of forming, in particular of superplastic forming, and having a coating according to the invention at least partially on one or on both sides of the metal sheet and a method for manufacturing a metal sheet or strip according to the invention comprising the steps of providing a metal sheet or strip capable of forming, in particular of superplastic forming, and applying a coating according to the invention.
Abstract:
The present invention relates to a method for applying hexagonal boron nitride to a rough surface, wherein it is intended for the boron nitride to be provided as a temperature-resistant lubricant of the surface. According to the invention, a pin composed of hexagonal boron nitride is rubbed with pressure over the rough surface, such that abraded boron nitride adheres to the surface.
Abstract:
Provided is a high durability thermally conductive composite containing 0.5-10 volume % of a high molecular weight silicone with vinyl groups on both ends with viscosity at 25 DEG C. of 10000-15000 Pa·s, 1-10 volume % of an alkylalkoxysilane, and 40-65 volume % of an inorganic filler with the remainder being an addition-reacting low molecular weight silicone with viscosity at 25 DEG C. of 0.2-0.5 Pa·s. Also provided is a grease characterized in containing 38-48 volume % of an addition-reacting low molecular weight silicone with viscosity at 25 DEG C. of 0.2-0.5 Pa·s, 2-8 volume % of a high molecular weight silicone with vinyl groups on both ends with viscosity at 25 DEG C. of 10000-15000 Pa·s, and 50-60 volume % of an inorganic filler. It is preferable that the alkylalkoxysilane is a triethoxysilane or trimethoxysilane wherein the number of carbons in the alkyl groups is six to ten.
Abstract:
The production of solid lubricant agglomerates by combining solid lubricant powder, an inorganic binder, other fillers if optionally desired, and a liquid to form a mixture, and driving off the liquid to form dry agglomerates which are subsequently classified by size or milled and classified by size to yield agglomerates of a desired size range. These agglomerates are then treated to stabilize the binder, thereby strengthening the binder and rendering it nondispersible in the liquid. The undesired size ranges can be readily recycled because the agglomerates with untreated binder can be reprocessed, thereby promoting high recovery rates.
Abstract:
Forge lubrication processes are disclosed. A solid lubricant sheet is placed between a workpiece and a die in a forging apparatus. Force is applied to the workpiece with the die to plastically deform the workpiece. The solid lubricant sheet decreases the shear factor for the forging system and reduces the incidence of die-locking.
Abstract:
The present invention is directed to an apparatus for distributing a cable-pulling composition onto a cable as it is being pulled through a conduit. In one embodiment, the cable pulling composition is a block of an enhanced composition, e.g., consisting essentially of boron nitride that facilitates the pulling of cables through conduits. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface through the use of the cable-pulling apparatus of the invention.
Abstract:
A reversible thermal thickening grease for microelectronic packages, in which the grease contains filler particles; at least one polymer; and a binder; in which the filler particles are dispersed within the binder, in which one or more segments of the at least one polymer may be attached to the filler particles prior to dispersion in the binder, and in which the polymer collapses at temperatures below a Theta temperature and swells at temperatures above a Theta temperature. During the operation of a microelectronic package, grease pump-out and air proliferation are minimized with use of the reversible thermal thickening grease, while grease fluidity is retained under repetitive thermal stresses.
