Abstract研究了耐热不锈钢1Cr11Ni2W2MoV在600,700和800℃空气和模拟煤油燃烧环境中的氧化行为,对表面生成的氧化物进行了表征,并讨论了环境介质对耐热不锈钢高温氧化行为的影响机制。结果表明:1Cr11Ni2W2MoV耐热钢在热空气中表面生成的氧化膜完整致密,表现出优良的抗氧化性能;而在模拟煤油燃烧环境中表面形成了疏松的氧化膜,并出现了瘤状氧化物,加速了不锈钢中Cr的消耗,明显降低了表面氧化膜的保护性。
Other AbstractMetallic materials exposed to fire scenes are usually subjected to high temperature oxidation,of which the atmosphere composition and temperature have been considered as vital parameters.In this study,the high temperature oxidation behavior of 1Cr11Ni2W2MoV stainless steel in air and simulated kerosene-combustion atmosphere at 600,700 and 800℃were studied by means of visual analysis and micro-structural observation of the formed oxide scale.The results show that the 1Cr11Ni2W2MoV possessed good oxidation resistance and the scales primarily remained continuous and well adherent to the substrate in air.Whilst,the presence of kerosene combustion products apparently increased the consumption of Cr element,reduced the adhesion of oxide scale and hence decreased the oxidation resistance of the steel.Additionally,the combustion products of kerosene resulted in the formation of nodular oxides in the formed scale.Therefore,the combustion of kerosene in fire scene could increase the oxidation rate of 1Cr11Ni2W2MoV,which are expected to offer complementary insight into reconstruction of fire scene.
