In powder metallurgy, powder metallurgy manufacturing process or used as a raw material to create metal materials, composite materials, and diverse products after being formed and sinterized. Powder metallurgy, which is a subset of powder metal sintering, is related to the manufacture of ceramics. As a result, a number of innovative sintering furnaces for powdered metal can also be utilized to create ceramic materials.
1. Preparation of raw material powder. Existing milling methods can be roughly divided into two categories: mechanical methods and physicochemical methods. Mechanical methods can be divided into: mechanical crushing and atomization; Physical and chemical methods are divided into electrochemical corrosion method, reduction method, chemical method, reduction-chemical method, vapor deposition method, liquid deposition method and electrolysis method. Among them, reduction method, atomization method and electrolysis method are widely used.
2. The powder is shaped into a blank with the desired shape. The purpose of molding is to give the blank a certain shape and size, and to give it a certain density and strength. Forming methods are basically divided into pressure forming and non-pressure forming. Pressure molding is widely used in pressure molding.
3. billet sintering. A crucial step in powder metallurgy sintering furnace technology is sintering. The raw billet can be sintered after it has been formed to give it the desired mechanical and physical characteristics. Unit sintering and multi-system sintering are two categories of sintering. The sintering temperature is lower than the melting point of the metal and alloy utilized for solid state sintering of unit system and multi-element system. The sintering temperature for liquid phase sintering of multi-component systems is often higher than the melting point of fusible component but lower than the melting point of refractory component. There are specialized sintering techniques such loose firing, melting soaking, and hot pressing in addition to standard sintering.
4. following product treatment. Following sintering, various processing techniques can be used depending on the demands of the final product. such as machining, heat treatment, electroplating, finishing, and so forth. Additionally, in recent years, powder metallurgy sintering furnace materials have been processed using rolling, forging, and other innovative methods, and the best outcomes have been obtained.
