The basic processes of powder metallurgy process.

1. Preparation of raw material powder. Existing powder making methods can be broadly divided into two categories: mechanical and physicochemical methods. The mechanical method can be divided into: mechanical crushing and atomization method; physicochemical method is divided into: electrochemical corrosion method, reduction method, chemical law, reduction – chemical law, vapor deposition method, liquid phase deposition method and electrolytic method. Among them, the most widely used is the reduction method, atomization method and electrolysis method.

2. Forming the powder into a desired shape. The purpose of forming is to produce a billet of a certain shape and size, and to make it have a certain density and strength. The methods of forming are basically divided into pressurised forming and non-pressurised forming. The most commonly used method of pressurised forming is moulding.

3. Sintering of billets. Sintering is a key process in the powder metallurgy process. After forming, the pressed billet is sintered to give it the required final physical and mechanical properties. Sintering is also divided into unit system sintering and multi-system sintering. For the solid phase sintering of unitary and multiple systems, the sintering temperature is lower than the melting point of the metals and alloys used; for the liquid phase sintering of multiple systems, the sintering temperature is generally lower than the melting point of the refractory components and higher than the melting point of the fusible components. In addition to ordinary sintering, there are special sintering processes such as loose-fitting sintering, melt-impregnation method and hot pressing method.

4.Post-processing of the product. After the sintering treatment, according to the different requirements of the product, to take a variety of ways. Such as finishing, oil dipping, machining, heat treatment and electroplating. In addition, in recent years, some new processes such as rolling and forging are also used in the processing of powder metallurgical materials after sintering, achieving more desirable results.
