Type and process of powder metallurgy in sintering furnace

Sintering furnace is a commonly used powder metallurgy equipment, which is used to burn metal powder into bulk materials by high temperature heating and pressure. Powder metallurgy is an important material preparation process, by pressing the metal powder into shape, and then sintering at high temperature, so that the powder particles are combined to form a dense bulk material. Here are some common powder metallurgy types and processes for sintering furnaces:

1. Metal powder sintering: Metal powder sintering is the most common type of powder metallurgy. In the sintering process of metal powder, the metal powder is first formed by pressing to form the desired shape and size, and then sintered at high temperatures in a sintering furnace. In the sintering process, the metal powder particles are diffused and combined to form a dense metal block material.

2. Ceramic powder sintering: Ceramic powder sintering is a method of preparing ceramic powder into ceramic materials by sintering process. Similar to the sintering of metal powders, ceramic powders are first formed by pressing and then sintered at high temperatures in a sintering furnace. In the sintering process, the ceramic powder particles are diffused and combined to form a dense ceramic block material.

3. Silicon carbide sintering: silicon carbide sintering is a special powder metallurgy process for the preparation of silicon carbide ceramic materials. In the sintering process of silicon carbide, the silicon carbide powder is first formed by pressing and then sintered at high temperature in the sintering furnace. In the sintering process, the silicon carbide powder particles are diffused and combined to form a dense silicon carbide ceramic material.

4. Tungsten alloy sintering: Tungsten alloy sintering is a powder metallurgy process for the preparation of tungsten alloy materials. Tungsten alloy powder is first formed by pressing and then sintered at high temperature in a sintering furnace. In the sintering process, tungsten alloy powder particles are diffused and combined to form a dense tungsten alloy bulk material.

The above are some common sintering furnace powder metallurgy types and processes, different materials and processes will have some subtle differences. Powder metallurgy process has the characteristics of high efficiency, flexibility and strong controllability, and is widely used in the preparation and processing of metals, ceramics and alloys.
