Title:
【発明の名称】高温で高い曲げ強度を有する炭化ホウ素サーメット構造材料
Document Type and Number:
Japanese Patent JPH10504063
Kind Code:
A
Abstract:
Prepare boron carbide-aluminum structural composites by infiltrating molten aluminum or aluminum alloy into a porous preform that is either unbaked or baked at a temperature of up to 1800 DEG C. to form a densified cermet and then heat treat the cermet in air or an oxygen-containing atmosphere to form a dense outer surface layer of aluminum oxide. The resulting structural cermets can withstand prolonged exposure to temperatures above the melting point of aluminum without suffering undue degradation of physical properties such as flexure strength.
