Abstract:
During the break-in period of track (22) assembly components, galling can occur between the components during use. The components include a pin (68) that is received within a bushing (70) and alternatively a sleeve bearing (74) between the pin (68) and the bushing (70) depending on the load. A method to prevent or reduce galling includes applying a coating (78) of zinc phosphate and a low-friction layer (76) on top of the zinc phosphate (78). The low-friction coating (76) can be made of WS 2 (Tungsten Disulphide), BN (Boron Nitride), MoS 2 (Molybdenum disulfide) or PTFE (Polytetrafluoroethylene) and deposited during a mechanical treatment.

Abstract:
Lubrication and friction reduction improves fuel efficiency and reduces energy consumption. Effective and controllable material removal results in superior surface finishing and planarization. Nanosheets are developed with specific functionalization that can be used to reduce friction and wear, improve the fluidic property, and rheological performance.. The nanosheets can be from the graphite family, transition metal dichalcogenides, transition metal trichalcogenides, semiconducting chalcogenides, metal oxides, layered hydroxides, clays, ternary transition metal carbides and nitrides, and zirconium phosphates and phosphonates, and their corresponding dopants. Tribological, rheological, and polishing applications include lubricants, viscosity modification, and chemical-mechanical planarization. The nanosheets are useful in improving efficiency and lifetime of machinery, saving energy for mechanical operations, and optimizing manufacturing processes in surface engineering.
Abstract:
An overbased calcium sulfonate grease composition comprising a reduced amount of overbased calcium sulfonate, added calcium carbonate, base oil, one or more converting agents, and one or more complexing acids if a complex grease is desired. The calcium sulfonate grease composition improves thickener yield and expected high temperature utility as demonstrated by dropping point. The calcium carbonate may be used to react with complexing acids when making a complex grease, such that the addition of calcium oxide or calcium hydroxide is not required. A method of making the composition comprising the steps of mixing the overbased calcium sulfonate and base oil, adding the calcium carbonate, adding one or more converting agents, and adding one or more complexing acids. All or a portion of one or more of the complexing acids may be added with or prior to the one or more converting agents.
