The surface films on the Si-bearing stainless steels formed after soaking in the concentrated nitric acid for 216 h have been investigated by means of an electron energy spectrometer.It can he reached that Si builds up in the surface in the form of SiO_2.It plays a main part as a passivating element in the Si-bearing stainless steels in strong oxidizing medium,whereas Cr drops down to the second place. 展开更多
