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, MoS2 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 DEG -800 DEG 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 DEG -800 DEG F. and is stable at such temperatures.
Abstract:
There is provided a galvanized steel sheet with high press formability, which has an inorganic compound on a metallic galvanized layer thereof. The galvanized steel sheet according to the present invention is manufactured by bringing the plating surface of the galvanized steel sheet into contact with a water solution containing 0.1 wt% or more of a borate of alkaline metal, and then drying the steel sheet by heating within a temperature range of 60 to 400 DEG C. The friction coefficient of the galvanized steel sheet of the invention is 80% or less of the friction coefficient obtained without the existence of the inorganic compound on the metallic galvanized layer and the amount of insoluble slimes of the inorganic compound left after water washing or alkali degreasing is less than 1 mg/m .
Abstract:
A rheologically controlled glass lubricant for hot metal working comprises a glass powder, a binder, a rheological agent, and a weetting and viscosity modifier. These materials may be dispersed in a carrier. The lubricant is made by mixing the constituent elements, milling the mixture, and stabilizing the milled mixture. The lubricant can be used in a forging operation by coating a metal part with the lubricant, heating the coated part, placing the coated heated part in a forge, and rapidly applying sufficient pressure to deform the coated metal part into a desired shape.
Abstract:
A solid lubricant composition comprises (I) 30 to 70 parts by weight of graphite, (II) 70 to 30 parts by weight of a mixture of at least two components selected from alkali molybdate, alkali or alkaline earth sulphate and alkali phosphate, the ratio of the two individual ingredients being in the range of from 0.05/1 to 20/1. Compositions give improved load-bearing capacity and allows settling of friction coefficient.
