DIFFUSION BONDING OF CERAMICS TO METALS

The Hot Isostatic Pressing (HIP) technology has bright technical potentials in the processing of powder materials. However, the HIPping technology is far from maturity in the field of diffusion bonding. The increasing requirements of materials for high-temperature performance in the aerospace industry further highlighted the significance of diffusion bonding; in particular, the bonding of ceramics to metals. This paper attempts to review Diffusion Bonding and some of the models proposed. In particular, it also compares the diffusion bonding techniques by mechanical method and HIP. HIP is shown to be more efficient and viable technique.
