Interactions between Ti Al alloy and AZC/AMT binder systems

发布时间：2021-01-05 23:18

　　In this work, two kinds of binders, Ammonium Zirconium Carbonate（AZC） and Ammonium Metatungstate（AMT） hydrate, and three kinds of powders（ZrO 2, Al2O3 and Y2O3） were mixed to fabricate six kinds of face coating systems. The thermal behaviors of the AZC and AMT dried binders were investigated by TG-DTA, and the phase transformation of the two binders was determined by XRD. Monoclinic ZrO 2 phase was formed from AZC at 620 °C and WO3 at 700 °C, and the phase transformation was completed at lower t...
