In recent years, graphene, conductive polymers and transition metal oxide composites have attracted more and more attention of researchers, and have become one of the foreword fields of electrochemical research.

Nanometer tungsten disulfide electrode material, with high specific capacity, large specific surface area and good thermal stability, is considered as an ideal energy storage electrode material, widely used in the field of electrical materials.

Thermal spraying of cemented carbide powder is a technology of hardening and strengthening mechanical surface. This technology may effectively prolong the service life of machinery. Tungsten carbide is the most common raw material for thermal spray welding (coating). Nowadays, there are many new technologies on the market, such as high-energy plasma spraying, vacuum plasma spraying, supersonic flame spraying, explosive spraying and so on. Whatever process is adopted, the raw materials for spraying are not made of high-quality tungsten carbide powder.

WS₂ grease has good lubrication performance, and can still play a good lubrication effect on mechanical equipment in high temperature, high pressure, high vacuum and other harsh working environments. What are the reasons for this?
