Abstract
Abstract Feather-like columnar structured 7YSZ thermal barrier coating (TBC) was prepared by plasma spray-physical vapor deposition (PS-PVD). An aluminum (Al) film was deposited on the TBC surface by magnetron sputtering. The Al-deposited TBC was vacuum heat-treated at 665 °C, 808 °C and 900 °C for 1 h separately. Then an α-Al 2 O 3 layer was observed on the top of 7YSZ coating, which resulted from in situ reaction of Al and ZrO 2 at high temperature under vacuum condition. The microstructure evolution and phase composition of the TBC were characterized by FE-SEM and XRD respectively. The CMAS (CaO–MgO–Al 2 O 3 –SiO 2 ) corrosion property of as-sprayed and treated Al-deposited TBC was compared, which was conducted at 1200 °C for 24 h. The results show that the Al-deposited TBC after vacuum heat treatment have better CMAS corrosion resistance than the as-sprayed TBC.
