A coated article includes a substrate, and a coating disposed on a surface of the substrate. The coating comprises a transition metal dichalcogenide (TMD). A method of forming a coating includes dispersing a transition metal dichalcogenide (TMD) and optionally tungsten carbide in a solvent to form a mixture, spraying the mixture on a surface of a substrate, evaporating the solvent, and forming a coating on the substrate comprising the TMD.

Coating comprising a transition metal dichalcogenide, and coated articles and methods relating thereto

A method of forming an inorganic film on a surface can include depositing a polymer at a layer on a surface, swelling the polymer with a solvent to produce a swollen polymer on the surface, infiltrating the swollen polymer with a precursor, removing the swollen polymer after infiltrating the swollen polymer with the precursor, and forming a porous inorganic film on the surface based on removing the swollen polymer.

The present disclosure provide for coatings, coated structures, methods of coating, methods of coating a structure, and the like. In an aspect, the coating is a tribocatalytically-active coating, where the tribocatalytically-active coating interacts with the hydrocarbon environment forming a protective carbon-based tribofilm on the surface of the coating, which can be actively formed (reformed) during use of the coated structure within the hydrocarbon environment.

Coatings that reduce friction and wear

The disclosure relates to a method for forming a low refractive index layer on a substrate. The method generally includes (a) applying a block copolymer layer on a substrate, the block copolymer including a polar polymeric block and a non-polar polymeric block; (b) swelling the block copolymer layer with a solvent to increase the block copolymer layer thickness; (c) depositing a metal oxide or metalloid oxide layer on polar polymeric blocks of the block copolymer layer; and (d) removing the block copolymer layer from the substrate, thereby forming a porous metal oxide or metalloid oxide layer on the substrate.

Low refractive index surface layers and related methods

A new insight on the lubrication of artificial joint components is presented. Addition of small amounts of nanoscale diamond particles to an artificial joint promotes a substantial improvement in friction and wear behavior of the artificial joint surfaces. Artificial joint implants are made from a variety of materials ranging from metal alloys to polymers. Suitable methods of applying nanoscale diamond particles to an artificial joint include (i) coating an effective amount of nanoscale diamond particles onto the artificial joint prior to implants; (ii) applying a composition to the artificial joint during an artificial joint implanting surgery, wherein said composition comprises a biocompatible carrier fluid and an effective amount of nanoscale diamond particles dispersed in the biocompatible carrier fluid; (iii) injecting the composition for lubricating the artificial joint into the artificial joint.

Superlubricating graphene and graphene oxide films

A method for designing new materials for superlubricity comprises developing, on a computational system, a computational supercell comprising x unit cells of a base material, each unit cell comprising y atoms of the base material. The computational system replaces randomly chosen z atoms of the base material with an impurity atom of an impurity material to form a candidate material. The computational system determines volumetric strain of the candidate material. In response to the volumetric strain exceeding a predetermined threshold, the computational system determines that the candidate material has superlubricity. The computational system displays the candidate material to a user if the candidate material has superlubricity.
