چکیده
The paper presents influence of mechanical surface damage on corrosion resistance of plates made of Cr-Ni-Mo stainless steel, used in funnel chest treatment. The surface of the steel was electrochemically polished and fitted. The surface damage is induced in the given deformation regions and is a potential reason of corrosion. The corrosion tests were realised by recording of anodic polarization curves with the use of the potentio-dynamic method. The VoltaLab® PGP 201 system for electrochemical tests was applied. Additionally, the tests showed that the structure of the steel the plates were made of, met the PN-ISO 5832-1 standard. On the basis of the obtained results it can be stated that that stainless steel can be applied in funnel chest treatment.
