摘　　要：国内钛及钛合金铸件主要采用石墨型和熔模铸造两种工艺方法生产,但由于技术局限性,实际生产过程中并不能完全满足客户对产品高质量、低成本、短交期的发展需求,因此非常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。消失模铸造具有独特的特点,在钢铁、铝等金属铸造中已获得广泛应用,但在钛合金中应用报道较少。本课题主要介绍了钛合金消失模覆壳铸造技术的优势和应用前景,以期为消失模铸造钛合金的应用提供参考。Domestic titanium and titanium alloy castings are mainly produced by machined graphite and investment precision casting.However,subject to technical limitations,the actual production process can’t fully satisfy customers’demand of high quality,low cost and short delivery time.Therefore,it is rather necessary to promote the research and application of new casting technology,thus complementing with the existing technology.Lost foam casting has advantages over other casting methods,which has been widely used in metal castings such as steel,aluminum,etc.,yet rarely reported in titanium alloys.The advantages and application prospects of titanium alloy were reviewed to provide reference for EPS lost foam cladding casting technology.
