Tungsten is an indispensable strategic metal in the defense field and plays an important role in the national military strategic reserve. In view of the current status of resources, the replacement of black tungsten by white tungsten is an inevitable trend. However, China's white tungsten resource endowment is poor, accompanied by more impurities such as molybdenum and phosphorus. 

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.

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.
