Abstract：
High quality support plate casting of ZTC4 titanium alloy with narrow cavity was prepared by the method of ceramic core and investment mold precision casting.The influence of ceramic cores of different materials on the thickness of layer on the surface of the casting cavity was tested.The application research of ceramic core removal process including mechanical method,alkaline cleaning method and hydraulic cleaning method was carried out.The results show that the zirconia ceramic core has high strength and good inertness,and the brittle layer on the surface of the casting is relatively thin,which can be used as the main material of the narrow cavity of the titanium alloy casting.The mechanical method and alkaline washing method cannot effectively remove the zirconia ceramic core in the narrow cavity of the casting,but the hydraulic cleaning method can effectively remove the ceramic core in the narrow cavity,and the comprehensive effect is relatively ideal.
