摘要:
Anti-wear and/or friction reducing formulations that include a mixture of at least one first ionic liquid and at least one ashless antiwear compound. The ashless antiwear compound can be a second ionic liquid or an ashless thiophosphate compound. The formulation desirably provides synergistic anti-wear and/or friction reducing properties. The first IL can be a monocationie ionic liquid or a dicationic ionic liquid. The second IL is a dicationic ionic liquid. The ashless thiophosphate is desirably a thiophosphate, such as a fluorothiophosphate (FTP), an alkylphosphorofluoridothiolate, or an alkylthioperoxydithiophosphate. Antiwear and/or friction reduction formulations comprising the above mixtures diluted up to 25% by weight in a base oil.

Lubricant additives that includes the alkylthioperoxydiphosphates.
摘要:
Disclosed are methods for preparing lubricant additives and lubricants by reacting together organophosphate compounds and fluorine compounds, the fluorine compound participating in the reaction as a reactant. The supernatants and precipitates formed during the reaction then may be used as lubricant additives.
摘要:
Amorphous SiOx (SiO2), SiONx, silicon nitride (Si3N4), surface treatments are provided, on both metal (titanium) and non-metal surfaces. Amorphous silicon-film surface treatments are shown to enhance osteoblast and osteoblast progenitor cell bioactivity, including biomineral formation and osteogenic gene panel expression, as well as enhanced surface hydroxyapatite (HA) formation. A mineralized tissue interface is provided using the amorphous silicon-based surface treatments in the presence of osteoblasts, and provides improved bone cell generation/repair and improved interface for secure attachment/bonding to bone. Methods for providing PEVCD-based silicon overlays onto surfaces are provided. Methods of increasing antioxidant enzyme (e.g., superoxide dismutase) expression at a treated surface for enhanced healing are also provided. Continuous generation and release of Si4+ ion into an in vitro or in vivo environment in the presence of osteoblasts/osteoblast progenitor cells, methods of employing same for enhancing the rate of bone healing/bone regeneration, is also described.
摘要:
Disclosed is a low-phosphorous lubricant produced by a process comprising forming a lubricant additive by reacting metal halide and organophosphate together to form a reaction mixture, the metal halide participating as a reactant, and adding at least a portion of the reaction mixture to a lubricant base comprising from about 0.01 weight percent phosphorous to about 0.1 weight percent phosphorous.
摘要:
A process and method for manufacturing an improved engine oil comprising mixing ferric fluoride with ZDDP to form an additive mixture, heating the additive mixture to at least 125° C. for at least 4 hours to produce a pre-reacted mixture, and adding the pre-reacted mixture to a fully formulated engine oil not containing ZDDP. Also disclosed is an engine oil prepared by a process comprising mixing catalyst with ZDDP to form an additive mixture, heating the additive mixture to about 60° C. to produce a pre-reacted additive mixture, and adding the pre-reacted additive mixture to a fully formulated engine oil not containing ZDDP.
摘要:
A additive is incorporated into a filter for use with engine oil such that when the engine oil passes through the filter media the engine oil, or components of the engine oil react with the additive inside the filter to produce compounds that increase the anti-wear and/or lubricating properties of the engine oil. The filter additive may be formed by an organic or metal fluoride material.
摘要:
A lubricant additive produced by the process comprising mixing an organophosphate and an organofluorine compound and reacting the organophosphate and the organofluorine compound to produce a reaction mixture comprising the lubricant additive. Also, a lubricant produced by the process comprising forming a reaction mixture by reacting an organophosphate and an organofluorine and adding at least a portion of the reaction mixture to a lubricant base.
摘要:
A method for forming in-situ a fluorinated organic compound or polymer film from the friction-induced reaction of an organic material, such as zinc dialkyldithiophosphate (ZDDP), and a fluoridated material, such as iron fluoride (FeF3) on or in proximity to a wear surface substrate. Also disclosed is a method for producing a lubricated wear surface by frictionally reacting an organic material and a fluoridated material near a wear surface, where the reaction product is a fluorinated organic compound bonded to the wear surface.
