Thermal spraying technology is a key technology in the field of surface modification. As a wear-resistant and corrosion-resistant coating, tungsten carbide/cobalt coating is widely used in aerospace, metallurgy, machinery and other fields because of its high hardness and good toughness. Compared with hard chromium plating, thermal sprayed WC-Co coating has obvious advantages in wear resistance, corrosion resistance, fatigue resistance and so on, and has the advantages of rapid preparation and less environmental pollution.

The life on earth is inseparable from the sun. With the development of science and technology, people realize that sunlight provides enough renewable green energy to achieve higher solar-thermal energy conversion efficiency and achieve more efficient water evaporation performance. The topic of photothermal materials----tungsten oxide nanofiber membranes is constantly being explored.

A variety of color-changing films can be seen everywhere in life, and the materials for making color-changing films are very wide. One of the new materials is the tungsten oxide electrochromic film.

Nano tungsten oxide heat-insulating glass is one kind of coated glass, which is produced through mixing a mixture of 5-10nm nano tungsten oxide and indium-phosphide oxide with resin and diluent, and then coat on the glass surface. The new coated glass has the advantages of good heat insulation performance, high transparency and good anti-UV effect, and is widely used in architectural glass curtain wall, vehicle and ship glass and other industries.
