A spring part, in particular for a driving device, includes a spring body extending around a central axis. The spring body comprises several spring windings which run radially around a spring axis and are made of at least a base material. The base material is surrounded at least by a first protective layer, and the spring body is at least partially covered on the outside by a lubricant. A method for manufacturing a spring part includes the steps of providing a spring body with several spring windings made of a base material and coating the base material at least with a first protective layer. The method includes the step of applying a lubricant formed as a silicone-based lubricant to the outside of the coated spring body.

The present disclosure relates to an anti-wear, anti-friction and stably-dispersed lubricating oil or grease, and the anti-wear, anti-friction and stably-dispersed lubricating oil or grease includes a main component of a lubricating oil or grease and a long carbon chain-grafted sulfonated graphene, the preparation method of which includes mixing a main component of a lubricating oil or grease with a long carbon chain-grafted sulfonated graphene, stirring and dispersing the mixture to obtain the product. The lubricating oil or grease in the present disclosure can significantly improve the long-term dispersion stability and dispersion stability in a complex environment by adding a long carbon chain-grafted sulfonated graphene in the main component, and at the same time can significantly improve the friction coefficient, which can significantly improve the anti-wear and anti-friction properties of the lubricating oil or grease, reduce the diameter of wear scars, and reduce the wear of copper and iron.

Compositions resulting from the mixing of at least: a comb polydiol copolymer A1 and a compound A2 including at least two boronic ester functional groups, the comb polydiol copolymer A1 including a main chain and side chains, at least a portion of the side chains of the copolymer A1 being composed of oligomers. They exhibit very varied rheological properties depending on the proportion of the compounds A1 and A2 used. Composition resulting from the mixing of at least one lubricating oil with such a composition of associative and exchangeable polymers and use of this composition for lubricating a mechanical part.
