Abstract

The nature of braze bonding by chemical redox reactions causing a diffusion zone on the surface of the nonmetal with the braze alloy is explained briefly. Some technical and economic advantages for tool and device manufacturing are discussed. Samples of monocrystal devices and grinding tools with braze bonded diamond grit demonstrate the potential of this technology particularly for miniaturization. New applications with other hard materials are shown.

Wearing tests have proved that the lifetime of tools with brazed on diamonds is several times as long as of conventional ones with formlocked diamonds. The reason for this is explained.
