Abstract: The present invention is drawn to an anti-lubricant in the form of a composition that is a viscous fluid, a paste, a gel or even a semi-solid rubber-like material. More specifically, the invention suggests the use as the anti-lubricant of a composition of two or more siloxanes chemically reacted together to form a desirably thick viscous fluid, paste, gel or rubbery solid reaction product, the resultant reaction product being admixed with a more liquid, mobile siloxane that itself has anti-lubricant properties, this more mobile siloxane, which may be either one of the two reacted together or a completely different one, is immobilized—stably dispersed—within the reaction product (and not only provides the required anti-lubricant property but may also be used to modify the final “viscosity” of the composition).

Abstract: There is described a method of securing against lateral motion two bodies held in face to face asperity contact to make a joint between the two bodies. Inserted into the interface between the two bodes is a material known as a galling agent, gall promoter, gall enhancer or anti-lubricant. This material is a composition of a crosslinked siloxane having dispersed therein a gall promoting silicone. The crosslinked siloxane is formed, for instance, from the reaction between an amino siloxane and a dicarboxylic anhydride siloxane.

Abstract: In a method for removing metal from the surface of a workpiece by continuously rubbing the surface with a tool in a friction-inducing manner and in the presence of a friction-enhancing agent (an anti-lubricant) and in which a thin layer of the friction-enhancer must be available at the tool surface, there is provided a tool which carries the friction-enhancing agent in the form of a composition of an abrasive and a rubbery solid siloxane reaction product admixed with a liquid, mobile, anti-lubricant siloxane stably dispersed therewithin, and the use of the tool to excoriate and condition the surface by removing therefrom the oxide film thereon and leaving its place a siloxane film, and a conditioned metal surface having siloxane molecules each individually bonded directly to the metal over a relatively large area of the surface to provide a relatively uniform siloxane layer.

Abstract: A composition which is effective in the making of a galled joint between two metal members in which there are gaps in the joint prior to and during its formation and which comprises a multiplicity of small metal particles and a gall-enhancing material, for example, a polydimethylsiloxane, and the use of the composition in a method of securing against lateral motion two bodies held in face to face asperity contact, thereby to make a joint between the two bodies, in which method there is inserted into the gap or interface between the two bodies said composition, which on minimal initial lateral relative motion of the two surfaces promotes rapid but controllable "galling" between the two surfaces, this galling binding the surfaces against further such motion.

Abstract: A method involving galling for securing against lateral motion two bodies held in face-to-face asperity contact, thereby to make a join between the two bodies, in which in the preferred form of the method there is inserted into the interface of the surfaces of the two bodies a material that on minimal initial lateral relative motion of the two surfaces promotes rapid but controllable "galling" between the two surfaces, the galling binding the surfaces against further such motion, and the use in such method of electric current during formation of the join to heat and soften the touching asperities, thus enabling them to deform and flatten more rapidly to bring other smaller asperities nearby into contact and thus increase the number of gall sites, and/or use of electric current after formation of the join to effect stimulation and/or acceleration of the formation of diffusion bonds across the opposed faces of the join.

Abstract: The invention relates to a method of making what may for convenience be regarded as friction joints--that is to say, joints between the touching surfaces of two parts that are held in contact (by a force as experienced in a light interference, not one sufficient to cause forging) and that would otherwise move laterally past one another parallel to the touching plane, the method involving some minimal initial lateral movement of the two surfaces sufficient to cause some asperity deformation, leading to welding and shearing under special conditions--the phenomenon of "galling"--but not sufficient to raise the bulk temperature of either to a level where bulk welding will occur.
