| 摘 要： | 分别用ZrO2含量为20％、30％、40％的磷酸盐高温包埋材包埋铸造纯钛试样,对照组用MT-3专用铸钛包埋材；铸造后进行X线探伤,扫描电镜和EDS能谱分析.通过X射线探伤技术与扫描电镜对钛铸件性能检测,确定ZrO2与磷酸盐包埋材料的最佳配比.结果发现,ZrO2含量为20％的磷酸盐高温包埋材试样孔隙较多,孔隙含量与对照组有显著性差异,ZrO2含量为30％和40％组试样孔隙含量与对照组无显著性差异.扫描电镜和能谱分析结果显示,ZrO2含量为20％的试样反应层最厚,ZrO2含量为30％和40％的试样反应层较薄,对照组试件反应层最薄.含30％的ZrO2的磷酸盐包埋材料具有较好的性能.

| Abstract: | The pure Ti castings were produced with high temperature phosphate investment materials containing 20%,30% and 40% ZrO2,respectively,by investment casting,and compared pure Ti castings was produced with special MT-3 investment materials. The optimized proportion between ZrO2 content and phosphate investment materials was presented through examining the properties of Ti castings by the XRD(X-ray diffraction) and SEM(scanning electron microscope) ,EDS(energy dispersive spectrometer) . The results show that th... |
