Si-SiC saldato per diffusione

Product Si-SiC material Diffusion bonding
Material Si-SiC
Processing Method Difussion bonding of a Si-SiC plate
Size

φ300

Application

The diffusion bonding process we are developing can  join members of different shapes without using intermediate materials.

The appeal of this technology is that it can create shapes that are difficult to machine while maintaining the characteristics of the base material.

This technology makes it possible to combine unique characteristics into a single structure by (1) deep hole shape, (2) internal flow channels, (3) addition or division of flow channels, etc., although the size is the same as that of conventional parts.

This technology contributes to the achievement of complex and multifunctional shapes required for various applications.
