Abstract:

Article Preview

In this paper, a preparation method concerning ceramic moulds with zirconia coating used for the investment casting of TiAl alloys has been described. The processing technology of ceramic moulds was verified successfully using the ceramic moulds with zirconia coating prepared by recommended processing parameters. Interfacial reactions between ceramic moulds and TiAl alloys examined by OM (optical microscope), SEM (scanning electron microscopy) and XRD (X-ray diffraction) are presented in this paper. The results reveal that the thickness of interfacial reactions layer was about 20 μm.
