Testing strategies for corrosive interactions of ceramics with semi-solid and molten metal alloys

For the suitability assessment of ceramics or refractory materials for tools, crucibles or handling aids in metallurgy and metals processing, e.g., for thixoforming or rheocasting, besides properties such as wetting behaviour, wear resistance, thermal conductivity and thermal shock resistance, mainly the corrosion behaviour against the processed alloy influences the service life of a tool material. This paper presents a testing strategy to characterise the corrosion properties.
