Abstract

The structure, morphology and high-temperature oxidation of composite powders made by high-energy ball milling of powders, mixture of aluminum, activated carbon and graphite in the ratio 95/4/1, were investigated. The ball milling was carried out in AGO-2U laboratory planetary mill with water cooling. The grinding medium consisted mixture of hexane, SPAN-80 (sorbitan monooleate), and paraffin. The content of SPAN-80 was varied within the range of 1 to 7.5% by weight (wt). It was found that oxidation of aluminum in composite powders proceeds in two clearly distinguished stages, and the oxidation rate is extremely high. The reasons for the high reactivity of aluminum in composite powders are discussed.

复合“铝-活性炭-石墨”粉末的制备及高温氧化

研究了铝、活性炭和石墨以95/4/1的比例混合制备的高能球磨复合粉体的结构、形貌和高温氧化性能。球磨机在AGO-2U实验室行星磨机上进行了水冷却。研磨介质为己烷、SPAN-80（山梨醇单油酸酯）和石蜡的混合物。SPAN-80的含量变化范围为1 ~ 7.5% （wt）。结果表明，复合粉末中铝的氧化分两个明显的阶段，且氧化速率极高。讨论了铝在复合粉末中具有高反应性的原因。图形抽象

期刊介绍： Oxidation of Metals is the premier source for the rapid dissemination of current research on all aspects of the science of gas-solid reactions at temperatures greater than about 400˚C, with primary focus on the high-temperature corrosion of bulk and coated systems. This authoritative bi-monthly publishes original scientific papers on kinetics, mechanisms, studies of scales from structural and morphological viewpoints, transport properties in scales, phase-boundary reactions, and much more. Articles may discuss both theoretical and experimental work related to gas-solid reactions at the surface or near-surface of a material exposed to elevated temperatures, including reactions with oxygen, nitrogen, sulfur, carbon and halogens. In addition, Oxidation of Metals publishes the results of frontier research concerned with deposit-induced attack. Review papers and short technical notes are encouraged.
