Alumina Metallized Ceramic Parts

Alumina Metallized Ceramic Parts

Jinghui has been focusing on the production and processing of precision ceramic structural parts for more than ten years. Our product production is mainly divided into 3 steps, forming – finishing – metallization. The production flow chart is shown below.

To ensure the quality of alumina ceramic structural parts, it is necessary to do a good job in every link. Here we focus on the metallization process.

There are many metallization methods on the surface of ceramic structural parts, among which the Mo-Mn method is widely used because of its mature and stable process.

Introduction to Mo-Mn Method

The process of Mo-Mn method is to coat a layer of metal powder (with Mo powder and Mn powder as the main raw materials) on the ceramic surface, and form a solidified and dense metallized layer through high-temperature sintering, thereby realizing the metallization of ceramics.

The reason why the Mo-Mn method is widely used in the metallization of various ceramics is:

· The process is mature and stable.
· High bonding strength, especially suitable for applications under harsh mechanical and climatic conditions.
· It can be repaired many times without damaging the metallization layer.
· The requirements for solder, metallization paste formula and sintering atmosphere are not very strict, and the process is easy to master.
