原位等离子喷涂（IPS）是一种制备具有原位生成的热稳定相的复合涂层的方法。在本研究中，机械合金化Al-12 Si，B2 O3和TiO 2粉末沉积到铝基板上使用大气等离子喷涂（APS）。结果表明，在涂层过程中，TiB_2和Al_2 O_3通过初始粉末之间的反应原位形成，并在过共晶Al-Si基体合金中均匀分散。此外，所获得的结果表明，在原位反应强度强烈依赖于喷雾条件。(C)2008 Elsevier B. V.保留所有权利。
In-situ plasma Spraying (IPS) is a promising process to fabricate composite coatings with in-situ formed thermodynamically stable phases. In the present study, mechanically alloyed Al-12Si, B2O3 and TiO2 powder was deposited onto an aluminum substrate using atmospheric plasma spraying (APS). It has been observed that, during the coating process, TiB2 and Al2O3 are in-situ formed through the reaction between starting powders and finely dispersed in hypereutectic Al-Si matrix alloy. Also, obtained results demonstrate that in-situ reaction intensity strongly depends on spray conditions. (C) 2008 Elsevier B.V. All rights reserved.
