Purpose: The purpose of the study is to evaluate resistance to electrochemical corrosion of wire made of Cr-Ni stainless steel, designed for use in endourological treatment. The influence of strain formed in the process of drawing and methods of wire surface preparation to corrosive resistance in artificial urine solution were analysed. Design/methodology/approach: Wire corrosion tests were carried out in the solution of artificial urine with the use of the system for electrochemical tests VoltaLab ®PGP201. Resistance to electrochemical corrosion was evaluated on the ground of recorded curves of anodic polarization by means of potentiodynamic method. Mechanical properties of wire were tested by means of static uniaxial tension test. Findings: Potentiodynamic tests carried out in artificial urine enabled to determine how the resistance to pitting corrosion of wire changes, depending on strain formed in the drawing process as well as on the method of wire surface preparation. Deterioration of corrosive properties of wire along with the increase in the formed strain hardening was observed. Research limitations/implications: The obtained test results proved the suitability of the applied research methodology for evaluation of electrochemical corrosion resistance of wire made of stainless steel designed for use in endourology. Practical implications: Test results are of significant utilitarian value because they can determine the relation between pitting corrosion resistance and the volume of strain formed in the wire drawing process, and consequently their mechanical properties. Originality/value: The analysis of the results of electrochemical corrosion resistance tests showed positive impact of wire surface treatment by means of electrolytic polishing and chemical passivation method on improvement of its corrosive properties. It must be emphasised that despite the increase in corrosion resistance, obtained thanks to surface treatment, it is necessary to use protective coating on wire used in urology.
