| Abstract: | The element distribution of passivated film formed on the Y added high silicon stainless steel surface in the 93%H 2SO 4 was studied by AES. The results show that 0 2%Y addition can increases the SiO 2 proportion in the passive film of stainless steel so that it makes the SiO 2 content more rich of passive film in the alloy. |
