Abstract:
The problem is to provide a protective coating-forming waterborne composition that can form, by a simple method comprising coating and drying onto a metal surface, a coating that is uniform with little unevenness and that has an excellent galling resistance and workability that are at least as good as the corresponding properties afforded by conversion treatment methodologies. ÄSolutionÜ Waterborne composition for forming protective coatings, that characteristically contains water-soluble inorganic salt and smectite-type clay mineral. The lubrication performance of the coating can also be improved when said composition additionally contains a lubricating component.

PURPOSE: To provide a parting agent for low-speed casting which does not pollute the working environment, has an excellent run property and lubricity, and has excellent washability of dies. CONSTITUTION: The parting agent for low-speed injection die casting consists essentially of an inorganic lubricant, spherical resin particles having an average particle size of 0.1 to 10 μm, organic carboxylic acid metal salt and water. The inorganic lubricant is 100 pts.wt., the spherical resin particles having the average particle size of 0.1 to 10 μm are 5 to 100 pts.wt., the organic carboxylic acid metal salt is 5 to 100 pts.wt. and the water is 100 to 1,000 pts.wt.
Abstract:
A lubricant to be sprayed onto the surface of a steel material for forming a lubricant coat on the surface of the steel material to be forged. The lubricant comprises a particulate lubricant composed of thermally melting resin mixed with inorganic lubricant. The particulate lubricant is applied onto the surface of a steel material to be forged. Before or after applying the particulate lubricant onto the surface of the steel material, the surface of the steel material is heated. Consequently, the thermally melting resin melts and coheres with the inorganic lubricant over the surface of the steel material, resulting in the formation of a uniformly thick lubricant coat over the steel material. The lubricant coat prevents the steel material from being burnt in a forging device even during hot forging. The lubricant coat is fit for the forging of hard to work steel material. The lubricant coat also contributes to the decrease in forging cost, without deteriorating the forging environment.
Abstract:
The electroviscous suspension is based on a mixture of aqueous silica gel with silicone oil as the liquid phase to which a dispersant is added. The dispersant consists of amino functional or silicon-functional polysiloxanes having a molecular weight above 800. The concentration of the dispersant is from 1 to 30% by weight and preferably from 5 to 20% by weight, based on the silica gel particles. Electroviscous suspensions such as these are distinguished by the fact that they are highly compatible with elastomeric materials, non-sedimenting, non-inflammable and physiologically acceptable. In addition, they are heat- and freeze-resistant over a wide temperature range and are largely unaffected by temperature and pressure in their viscosity.

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.
