EFFECTS OF ALTERNATING VOLTAGE(AV) MODULATING PASSIVATION AND POSTTREATMENT ON THE PASSIVE FILM OF STAINLESS STEEL
Abstract:
By means of electrochemical method, ellipsometry and AES analysis, the stability of the passive film formed after A.V. modulating passivation and post-treatment was studied. The results show that the defect points can be removed and the surface of the passive film is roughened through A. V. modulating passivation. The adsorption of Mo-Containing ion on the surface of the passive film during post-treatment becomes easier,which further increases the stability of the passive film. A more striking improvement of the stability of the passive film was observed on 302 stainless steel than cn 316 stainless steel.
