Various proportions of ZrO₂/CaTiO₃ powders were mixed and hot pressed at 1500°C/30 min for Ti casting. The hot‐pressed ZrO₂/CaTiO₃ composites were reacted with pure Ti at 1700°C/10 min in Ar. The interfacial reaction between Ti and ZrO₂/CaTiO₃ composites was investigated through X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, and energy‐dispersive X‐ray spectroscopy. The ZrO₂/CaTiO₃ composites with less than 10 vol.%, CaTiO₃, and a minor amount of residual TiO₂ were found. When the content of ZrO₂ was increased to larger than 10 vol.%, two Ca₂Zr₅Ti₂O₁₆ and CaZrTi₂O₇ phases appeared in the composites. The amount of CaTiO₃ and CaZrTi₂O₇ in the composites gradually decreased as the amount of ZrO₂ increased. When Ti came in contact with ZrO₂/CaTiO₃ composites with less than 10 vol.% ZrO₂, the resulting eutectic reaction produced a liquid phase and induced melting. When ZrO₂ was increased to more than 30 vol.% in the composites, Ca₂Zr₅Ti₂O₁₆ and CaZrTi₂O₇ changed completely to CaZrO₃, Ti₂O, CaO, and ZrO₂. With more than 30 vol.% ZrO₂, no other reaction phases occurred in the Ti side after contact with the ZrO₂/CaTiO₃ composites, which is conducive for producing ceramic composites for Ti casting applications.

Ti与ZrO2 / CaTiO3复合材料的组织演变及界面反应

将各种比例的ZrO ₂ / CaTiO ₃粉末混合并在1500°C / 30分钟热压以铸造Ti。热压的ZrO ₂ / CaTiO ₃复合材料与纯Ti在1700°C / 10 min下在Ar中反应。通过X射线衍射，扫描电子显微镜，透射电子显微镜和能量色散X射线光谱研究了Ti与ZrO ₂ / CaTiO ₃复合材料之间的界面反应。所述的ZrO ₂ /的CaTiO ₃的复合材料具有小于10体积％，的CaTiO ₃，和残留的TiO少量₂被发现了。ZrO ₂的含量如果将其增加到大于10体积％，则在复合物中出现两个Ca ₂ Zr ₅ Ti ₂ O ₁₆和CaZrTi ₂ O ₇相。的CaTiO量₃和CaZrTi ₂ ö ₇以ZrO的量在复合材料中逐渐降低₂增加。当Ti与ZrO ₂ / CaTiO ₃含量小于10体积％的ZrO _2接触时，共晶反应产生液相并引起熔融。当复合物中的ZrO ₂增加到30 vol。％以上时，Ca ₂ Zr ₅Ti ₂ O ₁₆和CaZrTi ₂ O ₇完全变为CaZrO ₃，Ti ₂ O，CaO和ZrO ₂。当ZrO _2的体积百分比大于30时，在与ZrO ₂ / CaTiO ₃复合材料接触后，在Ti侧没有其他反应相出现，这有利于生产用于Ti铸造应用的陶瓷复合材料。
