Title:
CLADDING PROCESS OF METAL MICRO/NANO-PARTICLE
Document Type and Number:
WIPO Patent Application WO/2008/071068
Kind Code:
A1
Abstract:
Surface treatment of metal micro/nano-particle, especially cladding process of
metal micro/nano-particle, solves a technical problem on the oxidization resistance
of metal nanoparticle. The process includes forming oxidation layer on the surface
of metal particle at 50°C-510°C in protecting environment of nitrogen
gas with addition of oxygen, softening of the oxidation layer in high temperature
furnace, and inert gases penetrating sufficiently into the surface oxidation
layer of the metal particle in a sealed vessel filled with N2 and He.
