Infrared light, especially near-infrared, has a significant thermal effect, which tends to cause temperature rise, which causes an increase in temperature, such as indoors or in a car. Infrared barrier materials generally refer to a class of functional materials that have a strong absorption or reflection of infrared light without affecting the transmission of visible light. 

Cobalt-tungsten carbide alloy thermal spray coating is the highest hardness wear resistant coating below 540 °C. Due to its combination of good hardness and toughness, it is widely used in aviation, aerospace, automotive, transportation, metallurgy, electric power, etc. Strengthen the wear resistance of the base metal and repair the worn fatigue parts.

Acrolein is an important fine chemical intermediate with a wide range of applications in coatings, paper, oil, medicine, and organic synthesis industries.  In recent years, with the increasing demand of animal feed additives such as methionine, glutaraldehyde, pesticides and water treatment agents on the market, and the large excess of bio-glycerol, the rapid development of the acrolein industry has been promoted.

In recent years, with the development of low-voltage electrical industry, various series of new circuit breakers have been introduced. These new circuit breakers require contact materials with smaller volume and higher breaking capacity. At present, the matching of AgWC₁₂C₃ and AgW50 is often used as asymmetrical and reasonable matching contacts of circuit breakers in AgWC-C electrical contact materials, so as to improve the arc resistance and material transfer resistance of AgWC-graphite electrical contact materials, which is the necessary condition for expanding the application range of AgWC-graphite contact materials and meeting the increasingly stringent performance requirements of circuit breakers for contact materials.
