1、 Correlation between the two

 

1. The high strength, high friction resistance and high pressure resistance required by the structural parts made of powder metallurgy are what ceramics are good at.

 

2. Therefore, powder metallurgy manufacturers can apply product powder to the powder making stage of powder metallurgy process and add silicon nitride powder to the raw powder, which can significantly improve the strength, wear resistance and thermal shock resistance of powder metallurgy structural parts.

 

2、 Silicon nitride application

 

1. It is mainly used in metallurgy, machinery, chemical industry, semiconductor and other industries. As a part of some equipment or products, it has achieved good application results.

 

2. In recent years, with the development of manufacturing technology and testing and analysis technology, the reliability of products has been continuously improved, so the application scope is expanding. After investigation and analysis, it is found that the products can be used in the field of powder metallurgy and can be well combined with the powder metallurgy industry to promote each other and develop together.

 

3、 Powder metallurgy technology

 

1. Powder metallurgy is a technology that uses metal powder (or the mixture of metal powder and non-metallic powder) as raw material to manufacture metal materials, composites and various types of products through forming and sintering.

 

2. Powder metallurgy generally goes through three processes: powder mixing, forming and sintering. There are similarities between powder metallurgy and its production.

 

3. The basic process is: raw material powder preparation - powder forming into the required shape of green block - sintering of green block - post-processing of products, in which the powder performance often determines the performance of powder metallurgy products to a great extent.

 

Silicon nitride product is an important structural ceramic material, which is closely related to powder metallurgy, but the two are not the same material, so we should distinguish clearly when selecting and use according to steps to reduce problems.
