Title:
METALLIC HOLLOW SPHERE BODIES, METHOD FOR PRODUCING METALLIC HOLLOW SPHERE BODIES, LIGHTWEIGHT STRUCTURAL COMPONENTS, AND METHOD FOR PRODUCING LIGHTWEIGHT STRUCTURAL COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2010/067967
Kind Code:
A2
Abstract:
The present invention provides a method for producing metallic hollow sphere bodies, comprising the steps of: preparing a sintered skeleton of metallic hollow sphere bodies; coating the surfaces of the skeleton of the metallic hollow sphere bodies with metal oxide powder having a mean particle diameter of 50 nm to 5 μm using a binder to form shaped sphere bodies; keeping the shaped sphere bodies at a temperature of 550°C to 700°C for 10 to 120 minutes under a protective atmosphere to reduce the shaped sphere bodies; and sintering the reduced shaped sphere bodies at a temperature of 700°C to 1350°C under a protective atmosphere.
