Corrosion mechanism of Mo-W-ZrO2 cermet in molten steel

Optimization of corrosion resistance and mechanical properties of Al2O3‐Cr2O3 refractories for waste incinerator

“…29 Works by Zhang et al showed that the corrosion resistance to molten steel of Mo-35W-35ZrO 2 cermet was improved due to the formation of ZrO 2 layer on the cermet surface. 30 At the same time, the corrosion layer formed by residual ZrO 2 hindered the penetration of molten steel with the increase of ZrO 2 content, leading to the signif-icantly increased corrosion resistance to molten steel of BN-ZrO 2 -SiC composites. 31 Besides, research by Liao et al showed that BN-SiC composites with addition of nano ZrO 2 exhibited excellent steel corrosion resistance due to the improvement of compactness and the formation of ZrO 2 protective layer.…”

Superior Radiation Resistance of ZrO2-Modified W Composites

“…A series of results have demonstrated that dispersing fine oxide particles such as Y 2 O 3 [31], La 2 O 3 [32], TiC [33] and ZrC [34] in the W matrix can improve the toughness though strengthening the grain boundaries and increasing the recrystallization temperature. According to the previous research, we used the azeotropic distillation method combined with powder metallurgy method to fabricate W composites reinforced with c-ZrO 2 [35]. Further, through adjusting ZrO 2 content and swaging process to refine grain size and strengthen matrix, high strength and ductility W-ZrO 2 materials can be achieved.…”
