Abstract
Abstract The corrosion behaviour in a non-deaered 1M H 2 SO 4 solution of 304L stainless steel (SS) in bulk and thin film state was investigated. In the first step, we elaborated based cubic-centred 304L stainless steel thin films onto Si and f.c.c. 304L SS bulk substrates by using a sputter deposition method. Then, the structure and residual macrostress state of the films were studied by X-ray diffraction. It was found that films are in a highly compressive state (≈3 GPa). Finally, corrosion tests revealed an improvement in corrosion resistance of the films with respect to the bulk 304L stainless steel.
