Applications of soft X-ray absorption spectroscopy to the study of passive and oxide layers on stainless steels: influence of ion implantation
نویسنده
چکیده
Soft X-ray absorption spectroscopy (XAS) has been used to study the influence of Si ion implantation on the passive layer of AISI 304 stainless steel, as well as on its high-temperature oxidation behaviour. Ion implantation is a usual technique to improve the corrosion and oxidation resistance of steels. To study the effects of ion implantation on the room temperature corrosion behavior of AISI 304 stainless steel, XAS was performed on the passive layer formed spontaneously in contact with air. To analyse the effects of ion implantation at high temperatures, the oxide layer formed after an isothermal oxidation at 9008C for 32 h was also studied. The results show a positive influence of Si ion implantation on the corrosion behaviour of AISI 304 stainless steel. XAS in the soft X-ray excitation mode has proved to be a very suitable technique to perform corrosion science studies. 2001 Elsevier Science B.V. All rights reserved.
