The invention concerns a threaded tubular component for drilling or working hydrocarbon wells, said tubular component having at one of its ends (1; 2) a threaded zone (3; 4) produced on its outer or inner peripheral surface depending on whether the threaded end is male or female in type, characterized in that at least a portion of the end (1; 2) is coated with a lubricating dry film (12) the matrix (13) of which comprises at least one migrating sliding agent (9) belonging to the oils or waxes family and principally distributed at the surface of the lubricating dry film (12) such that the coefficient of friction of the film (12) is less than 0.07 at loads of less than 40 N while the coefficient of friction of the film (12) is more than 0.1 at loads of more than 200 N.
Abstract:
Substantially homogenous compositions in accordance with the present disclosure can exist in various forms, such as bulk materials, coatings, films, laminates, inserts, or overlays, and include at least one polymer such as SU-8, at least one liquid lubricant, and optionally at least one nanomaterial that serves as an inorganic filler material. Such compositions exhibit enhanced tribological and mechanical properties compared to the at least one polymer in isolation, for instance, a 50% or greater coefficient of friction reduction, a 100% or greater wear life increase, a 10% or greater elastic modulus increase, and/or a 10% or greater hardness increase. The at least one nanomaterial can include a first nanomaterial providing increased hardness, and a second nanomaterial providing increased elastic modulus. Compositions in accordance with the present disclosure are suitable for biological and non-biological applications.

Abstract:
The present invention provides a lubricating oil composition for reducing a friction coefficient adjacent to the surface of being subjected to lubrication. In particular, the present invention provides nanoporous particles capable of being dispersed in a lubricating oil composition comprising base oil having a lubricant viscosity. Since the nanoporous particles having nano-sized, oil soluble pores according to the present invention reduces a friction coefficient, and in the long term, gradually releases an effective ingredient, the lubricating oil composition comprising the same of the present invention can act as a reducing agent for reducing friction for a long period of time, and thereby, exhibit excellent lubricant effects.
