Dynamic generation of interface layers in a Spark Plasma Sintering Device (A06)

这个特殊项目的主要重点是检查缺陷尖晶石结构（γ-或η-Al2O3）的能力，以及有意生产的基于M2+Al3+2O2-4 （M = Fe, Mg， Mn和Cr）的缺阳离子尖晶石相，这些相形成于过滤器表面，以去除钢和铝合金熔体中的夹杂物和其他污染物。此外，还将分析在子项目A01和A02中开发的金属熔体与环保和含ca涂层之间界面的反应过程。样品将使用SEM/EDX， EBSD， EPMA和XRD进行表征。所选样品的界面将使用TEM和HRTEM进行分析。SPS技术在金属熔体生产中的应用范围将通过开发和测试替代工具材料而扩大。

The main focus of this particular project is the examination of the capability of defect spinel structures (γ- or η-Al2O3) and intentionally produced cation-deficient spinel phases based on M2+Al3+2O2-4 (M = Fe, Mg, Mn and Cr) that form on the filter surface to remove inclusions and other contaminations from the steel and aluminium alloy melts. Furthermore, the analysis of the reaction processes at the interface between the metal melts and the environment-friendly and CA-containing coatings developed within the subprojects A01 and A02 will be pursued. The samples will be characterised using SEM/EDX, EBSD, EPMA and XRD. Interfaces of selected samples will be analysed using TEM and HRTEM. The scope of the applications of the SPS technique for the metal melt production will be enlarged through the development and testing of alternative tooling materials.
