Novel Zirconate Based Moulds for the Investment Casting of Titanium Alloy Melts

摘要

Titanium alloys are key materials in aerospace as well as in biomedical and chemical industries due to their high strength combined with a low density and an excellent corrosion resistance. Investment casting allows the near net shaping of complex cast parts, using a ceramic refractory mould, which is produced by the lost-wax process, and filling it with the liquid metal melt. After solidifying, the ceramic mould is removed by breaking the shell. Fig. 1 provides a general model of the ceramic coats produced by dip-coating and stuccoing on the wax pattern.
