摘要
采用电弧离子镀技术在IC10合金基体上制备NiCrAlYSi粘结层,利用电子束物理气相沉积(EB-PVD)技术在粘结层上制备YSZ陶瓷面层。研究了YSZ热障涂层对IC10合金拉伸、持久、疲劳性能的影响。结果表明:IC10合金沉积YSZ热障涂层后,980℃/200MPa高温持久寿命与IC10合金相当;900℃高温抗拉强度σb、屈服强度σ0.2、伸长率δ和断面收缩率ψ与基体相比,基本保持不变;室温抗拉强度σb、屈服强度σ0.2与基体相比稍有下降;800℃/447MPa疲劳寿命与基体合金相当。因此,IC10合金沉积TBCs涂层后,对IC10合金力学性能无明显影响,不影响合金的实际使用。
The Y2O3 stabilized ZrO2 thermal barrier coatings with arc ion plated NiCrAlYSi bond coating were deposited by EB-PVD technique on the IC10 alloy substrate. The effect of YSZ thermal barrier coating on the tensile strength,yield strength at 900℃ and the rotating bending fatigue life were studied. Compared IC10 alloy with thermal barrier coating to ICIO alloy,the results of the stress rupture life under 980℃/200 MPa conditions, the tensile intension and yield intension at 900℃ and the rotating bending fatigue life under 800℃/447 MPa were identical. But it＇s room temperature tensile strength and yield strength decreases in some sort. So the EB-PVD TBCs process does not affect the mechanical properties of ICIO substrate.
