Abstract:
A granular solid wax particle comprising a highly paraffinic wax having a low T10 boiling point less than 427 °C and an inorganic powder coating; optionally with a layer of higher boiling wax over the highly paraffinic wax having a low T10 boiling point, and an inorganic powder coating over the layer of higher boiling wax. In separate embodiments, a highly paraffinic wax having a T10 boiling point less than 427 °C or a highly paraffinic wax having a needle penetration greater than 3 mm/10 at 25°C is coated with a powder that adsorbs the wax without being encapsulated by the wax in a hot drop wax test. Also, a process for transporting highly paraffinic wax having a T10 boiling point less than 427 °C as granular solid wax particles. And, a method of making base oil from granular solid wax particles transported from a distant location.

Abstract:
The inventive composition for forming a neoformed layer on wearing surfaces relates to mechanical engineering. Said composition makes it possible to form a neoformed layer on wearing surfaces while repairing and servicing different machines and mechanisms. Said layer exhibits a self-regeneration effect in operation and high tribotechnical characteristics, increased wear and corrosion resistance. The invention is characterised in that natural nickel-iron-magnesian hydrosilicates are used in said composition in the form of a base and catalyst, for example forsterite Mg 2 (SiO 4 ) or fayalite Fe 2 (SiO 4 ) or the like or the mixture thereof, promote the production of the neoformed layer on the wearing metal surfaces and initiate mass-exchange self-oscillation process.

Abstract:
The invention relates to mechanical engineering and can be used for modifying the wearing surfaces of cinematic pairs. The inventive method for forming an antifriction coating for the wearing surfaces of cinematic pairs consists in introducing a ground mineral composition between the wearing parts. Said composition forms a serpentine Mg3Si2O5(OH)4-containing antifriction coating, said serpentine being embodied in the form of the polymorphous modification thereof, i.e. chrysotile provided with a monoclinic system having co-ordination numbers 5.0

Abstract:
According to the invention there is provided a liquid friction control composition characterized as either having a high and positive friction characteristic or a low and neutral friction characteristic, comprising a retentivity agent. The liquid friction control composition may also comprise other components such as a solid lubricant, a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems.
