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

这一特殊项目的主要重点是检查缺陷尖晶石结构(γ-或η-Al_2O_3)和故意产生的基于M2+Al_3+2O_2-4(M=Fe、Mg、Mn和Cr)的阳离子缺陷型尖晶石相的能力，以去除钢和铝合金熔体中的夹杂物和其他污染物。此外，还将对分项目A01和A02中开发的环保型和含CA涂料与金属熔体之间的界面反应过程进行分析。样品将用扫描电子显微镜/能谱、EBSD、EPMA和X射线衍射仪进行表征。所选样品的界面将使用透射电子显微镜和高分辨电子显微镜进行分析。通过开发和试验替代模具材料，将扩大SPS技术在金属熔体生产中的应用范围。

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.
