テルミット型反応生成粒子分散アルミニウム合金とその耐焼付き性 Particle Dispersion Aluminum Alloy Produced by Thermit Reaction and Its Anti-seizure Property
The process of producing alumina particle dispersion Al-Si alloy slurry, and the wear properties of the product has been investigated. A thermit type reaction occurs when SiO<sub>2</sub> particles are added to the molten aluminum alloy. Consequently, hard alumina particles are distributed in the matrix alloy. The content of silicon in the matrix alloy increases because of reduction of the silica by molten aluminum. The potential ability of this method was clarified by measuring the rate of particles recovery and comparing with the conventional method of adding alumina particles. The composite had as good an anti-seizure property as the alumina aluminum alloy composite made by the conventional method.
