摘要

国内钛及钛合金铸件主要采用机加工石墨型和熔模精密铸造两种工艺方法生产

但受制于技术

实际生产过程中并不能完全满足客户对产品高品质、低成本、短交期的发展需求

因此有必要推进铸造新技术的研发及应用

与现有技术形成互补。消失模铸造具有其他铸造方法所不具备的优势

在钢铁、铝等铸件中已获得广泛应用

但在钛合金中应用报道较少。主要对钛合金消失模覆壳铸造优势、技术方案及应用前景进行了综述。

Abstract

Domestic titanium and titanium alloy castings are mainly produced by machined graphite and investment precision casting. However

the actual production process can hardly meet the requirement of high quality

low cost and short delivery time subject to technical limitations. Therefore

it is necessary to promote research and application of new casting technology to form a complement with the existing technologies. Lost foam casting has superior advantages

which has been widely used in metal castings such as steel

aluminum

etc.

while rarely reported in titanium alloys. The advantages

technology schemes and application prospects of titanium alloy lost foam cladding casting were mainly introduced.
