Advantages of air pressure sintering of cemented carbide Pin

Tire Studs is made of Tungsten Carbide Pin and steel body. In recent years, the air pressure sintering process of cemented carbide products has been extensively studied in various countries. Of course, it is not limited to product sintering materials. It has also made great progress in practical applications. It has now become a high-performance cemented carbide product. An important sintering technology.

The air pressure sintering process of cemented carbide products has many advantages: because the sintering hot isostatic pressing process is directly pressurized and held at the vacuum sintering temperature, it is beneficial to improve the fluidity of the liquid metal, eliminate voids, and avoid conventional types. Structural defects such as "coarse crystals" that are prone to appear after hot isostatic pressing; carbon balance is easier to control compared with vacuum sintering, which can correct the problem of carbon deficiency or carbon excess in pressed products, reduce internal pores in alloys, and improve cemented carbide products. Performance indicators such as strength and hardness have been improved to a certain extent; this process is carried out in the same furnace body, which saves a lot of equipment investment, and its processing cost is twice as low as that of vacuum sintering and hot isostatic pressing, which the carbide pin can greatly improve product use life.
