摘要 采用溶胶-凝胶方法于900℃的烧结温度下在SUS430合金表面制得LSC涂层,对涂层的物相、表面和断面形貌进行了分析和观察,空气氛围中测试了SUS430/LSC样品的ASR值随温度的变化和800℃下的氧化增重。结果表明,制得的SUS430合金LSC涂层为单一的钙钛矿相;涂层致密、与基体结合紧密、厚度均匀;SUS430/LSC样品的ASR值随着温度的升高呈下降趋势,温度高于400℃时与SUS430合金的ASR值差别不大;SUS430/LSC的氧化增重速率低于SUS430合金,涂层改善了SUS430合金的高温抗氧化性能。 The LSC coating of SUS430 alloy was prepared using sol-gel method sintered at 900 ℃ . The phases, surface morphology and the cross-section morphology of LSC coating were investigated, the temperature dependent ASR and the oxidation weight gain at 800 ℃ of SUS430/LSC were tested under air atmosphere. The results showed that the LSC coating of SUS430 alloy was single perovskite phase. The coating was dens and combined with alloy matrix closely with uniform thickness. The ASR value of SUS430/LSC decreased as the temperature increased, and when the temperature higher than 600 ℃ the ASR value of SUS430/LSC was close to that of SUS430 ahoy. The rate of oxidation weight gain of SUS430/LSC was lower than that of SUS430 ahoy, which indicated that the high temperature oxidation resistance of SUS430 ahoy was improved.
