Résumé | The focus of this study is the amorphous and crystalline phase formation in air plasma sprayed alumina yttria stabilized zirconia coatings. In this multi-component system at compositions close to its eutectic, amorphous structures can arise by virtue of the high cooling rates of melted particles. Two avenues for amorphous phase formation have been identified: in-flight and upon-impact mixing. While the crystalline structure is largely retained by unmelted or partly melted feed particles embedded in the coating, it can also be created in the solidification process. The formation of a supersaturated crystalline phase is proposed. It was found that the formation of the crystalline phases with supersaturated composition in alumina YSZ composite is possible, in spite of the high cooling rates during spray process. |
