Diffusion Bonding

Home> Technique> Diffusion Bonding

What’s diffusion bonding?

It joins metal materials by using diffusion of atoms generated between facing surface through their adhesion.
There is less thermal stress or deformation after joint and it features less deterioration of materials by structure change. And bonding of different
materials whose properties are different and complex forms of bonding are possible.

Features

  • - There is no any solidification structure (Doesn’t have any defects of solidification crack and blow holes).
  • - Doesn’t need weld metal and solder materials (Forms joints of uniform chemical components)
  • - Bonding of different materials is possible (Ceramic <-> Metal, steel, <-> Aluminum, steel <-> Copper alloys)
  • - Reliability and strength of joints are high (Equivalent to that of the basic materials.)

Applied products

Mold cooling C/T

  • Improves the problems about excessive time of cooling according to lack of uniformity of cooling passage as diffusion bonding of bed and
    lower plates is done, not the method to work it with drilling in the past.

Extends life of punch according to bonding of different materials (In case of carbide piercing punch.)

  • Carbide punch – Carbide (Functional part) + SKD11 (Structural part) = can extend more than two times of life.
