Powder metallurgy is a process technology for preparing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, forming and sintering, to produce metal materials, composite materials and various types of products. Powder metallurgy has similarities with the production of ceramics. Therefore, a series of new powder metallurgy technologies can also be used f
Powder metallurgy is a fast, high-speed, and suitable for mass production of small or no cutting machine parts production technology. The rapid development of powder metallurgy technology has been widely used in life, mainly because its technology has the following characteristics:(1) The material utilization rate is relatively high, which can reach more than 95%;
Powder metallurgy is a process technology for preparing metal or using metal powder (or a mixture of metal powder and non-metal powder) as a raw material, forming and sintering, manufacturing metal materials, composites and various types of products.
The common forming method of powder metallurgy materials is to compress metal powder in a rigid closed mold, which has high cost. Due to the poor fluidity of the powder and the influence of friction, the dense density is usually low, the distribution is uneven, the strength is not high, and it is difficult to move along the pressing direction Form thin-walled, elongated and variable cross-section
