摘　　要：制备了一种钛合金熔模铸造用新型氧化钇涂料,碳酸锆铵为粘结剂,氧化钇级配粉为耐火材料。该氧化钇涂料主要用作型壳的面层、次面层,研究了粉液比对涂料性能的影响。试验结果表明,粉液比为3.0 g/mL时,涂料性能最优,涂挂性最好。A novel yttria coating for titanium alloy investment casting was prepared： the binder is ammonium zirconium carbonate, and refractory is graded yttria powder. The yttrium oxide coating was mainly used as the shell surface, sub-surface layer. The effects of powder-liquid ratio on coating properties were analyzed. The experimental results show that with the powder-liquid ratio of 3.0 g/mL, the coating performance is optimal and the hanging property is the best.
