Overview of powder metallurgy process and its advantages

Powder Metallurgy (PM) manufacturing process offers a more flexible and adaptable method for mass production of required components compared to traditional methods such as casting precision components. The combination of optimised manufacturing techniques and new material systems allows the production of this material. Powder metallurgy increases the utilisation efficiency of materials with high density and excellent mechanical properties, reduces the need for machining, reduces complex shapes, allows the configuration of various variables and with a wide range of property variations. Eliminates possible waste and guarantees a high production rate. In powder manufacturing, the three main methods are mechanical, chemical, and physical powder manufacturing methods. However, the powder metallurgy process comprises of four necessary steps: powder manufacturing, powder mixing, compression, and sintering. Compression is done at room temperature and the high-temperature sintering process at atmospheric pressure. In this paper, an overview of the powder metallurgy process, the processing steps required to obtain complex shapes, material properties, commonly used manufacturing approaches, and the advantages of using this method in many industries, also describes the manufacturing process.
