摘要

复杂曲面钛合金叶轮铸件采用机加工石墨铸型或熔模精密铸造方法生产成本高、周期长。利用消失模工艺方法,生产出复杂曲面的钛合金叶轮铸件,而且化学成分和力学性能测试均满足使用要求,具有低成本、质量高、生产周期短的优势。
        Complex curved surface titanium alloy impeller castings were produced using machined graphite or investment casting with the shortcomings of high cost and long production cycle. In the present research,the study on lost foam casting process of complex curved surface titanium alloy impeller was carried out,and quailed castings were successfully produced. The chemical composition and mechanical properties of the castings all meet the requirements of technical specification, The method for producing impeller has the advantages of low cost, high casting quality and short production cycle.
