摘要/Abstract

摘要：

针对航空空心叶片氧化铝基陶瓷铸型高温性能较差的问题，研究了不同浸渍材料对氧化铝基陶瓷铸型高温性能的影响规律。结果表明：未经强化处理的陶瓷铸型力学性能较差，高温（1 500℃）强度不足0.5 MPa，室温（20℃）强度不足10 MPa。经硅溶胶、硅酸乙酯水解液、YCl₃溶液以及MgCl₂溶液4种不同浸渍液强化处理后陶瓷铸型力学性能有不同程度的提高，其中YCl₃溶液以及MgCl₂溶液强化效果不理想，陶瓷铸型力学性能没有明显改善，且MgCl₂溶液浸渍强化后陶瓷铸型存在较大的体积膨胀，不能满足使用要求；硅溶胶、硅酸乙酯水解液浸渍强化可显著改善陶瓷铸型的高温性能，硅溶胶强化处理后，陶瓷铸型1 500℃高温强度可达10 MPa左右，满足空心涡轮叶片定向凝固过程中对铸型高温强度的要求。通过复合浸渍的方法制造了一体化陶瓷铸型并成功浇铸了空心涡轮叶片。

Abstract:

To solve the problem that alumina-based ceramic molds usually perform badly at high temperature, different kinds of impregnating materials have been compared. Results show that molds without strengthening perform badly with the strength less than 0.5 MPa (1 500℃) and 10 MPa (20℃), while molds with strengthening perform differently. Molds impregnated with YCl₃ or MgCl₂ solution are not ideal, and there is a big expansion in the molds impregnated with MgCl₂ solution, which do not meet the application requirements. While by impregnating with silica solution or ethyl silicate hydrolyzate, the mechanical property of ceramic molds can be improved significantly. After impregnating with silica solution, the high-temperature strength is improved to 10 MPa (1 500℃), meeting the demand of fabricating blades during unidirectional solidification. Shrinkage of the molds is restrained by compound impregnating, and at last a hollow turbine blade is successfully fabricated by casting.

Key words: turbines, integral ceramic mold, alumina-based ceramic, high-temperature strength, impregnating strengthen
