| Abstract: | Silicon-aluminizing process was employed on HK40(25Cr-20Ni)high-temperature resistant steel(HTRS) for ethylene cracking tube.The feature of the microstructure of the silicon-aluminizing coating and its anti-carburizing property were analyzed and studied.The results show that the silicon-aluminizing treatment layer consists of adhere coating,interdiffuse coating and diffusion coating.After pack-carbonization for 100 h,the treatment layer still has quite good anti-carburizing property. |

| Keywords: | HTRS silicon-aluminizing anti-carburizing |
