【摘要】 对ZG30Cr30Ni8Si2NRE耐热钢和 1Cr18Ni9 在 900℃和 1 100℃下进行抗氧化性试验研究,结果表明:试验后ZG30Cr30Ni8Si2NRE组织中碳化物颗粒变小,铁素体数量增多;ZG30Cr30Ni8Si2NRE在 900℃下完全抗氧化,在1 100℃下抗氧化,表面形成了保护性氧化膜,其抗氧化性能明显优于1Cr18Ni9的抗氧化性能。更多还原

【Abstract】 The oxidation resistance tests of ZG30Cr30Ni8Si2NRE and 1Cr18Ni9 at 900℃ and 1100℃ were studied. The result shows that the carbide particle is diminished and the ferrite quantity increases after test. It also shows that ZG30Cr30Ni8Si2NRE is totally oxidation resistant at 900℃ and oxidation resistant at 1100℃, It′s surface has formed protective oxidation film and its oxidation resistance is obviously superior to 1Cr18Ni9′s.更多还原
