摘要
随着纳米材料技术的不断发展,纳米材料的制备技术已成为研究的重要领域。为了研究新的纳米陶瓷粉体(A l2O3)制造技术,在对电弧喷涂技术进行相关试验后,提出了改变电弧喷涂雾化气体成分,利用电弧喷涂原位反应合成技术,成功地制备了A l2O3纳米粉体材料。试验研究表明:在电弧喷涂雾化气体中加入纯氧气成分后,经高温电弧热熔化、雾化的铝金属粒子与氧气能够产生强烈的氧化反应,可以制备出A l2O3纳米粉体材料。
With the millimicron material technology uninterrupted growth, the millimicron material preparation technology already becomes the important field studying. For study new millimicron ceramics powder( Al2O3 )preparation technology, after the related researches on the arc spraying technology, it is quoted in the text that arc spraying can be synthesized by the change of the elements of the manufacturing technology of Al2O3 millimian powder by reactively synthesized arc spraying has been studied experimentally. The results from the experiment show that the participancy of heated and atomized aluminium dynamically oxidizes into Al2O3 powder.
