COMPOSITE SOLDER POWDER COMPRISING CORE AND METALLIC SHELL, FOR SOLDERING TURBINE COMPONENTS

摘要

The powder particle (10, 18) for soldering turbine components, comprises a non-metallic core with a metallic shell, which is formed around the core through a diffusion layer. The diameter of the powder particles lie in nanometre range. The material of the shell has lower melting point than the core. The shell has amdry-powder. The grain size of the powder particle is = 500nm. Independent claims are included for: (1) a component; and (2) procedure for soldering a component.
