    Abstract

    NiCoCrAl-Y2O3 and Al2O3-13% TiO2 (mass fraction) coatings, formed with means of laser cladding on nickel-based alloy, are heated using high frequency induction sources. The coating and the cross-section are analysed by SEM, XRD, and EDS respectively. The results show that, MCrAlY/Al2O3-13% TiO2 ceramic coating has an excellent chemical combination due to elements obvious diffused in the interface. It is found that Al2O3-rich submicron particles embedded in the TiO2-rich matrix, three-dimensional net structure formed in ceramic coating, which could decrease inner stress between different materials. Meanwhile, thermal shock experiment of samples is tested which shows that Al2O3-13% TiO2 ceramic coating have excellent high temperature property.
