Purpose: The work presents the influence of the surface treatment of Ni-Ti alloy, intended for implants applied in urogenital surgery, on their corrosion resistance. The tests were carried out in the simulated urine at the temperature 37 plmin 1 degree centigrade and pH = 5.6-6.4. In particular, the pitting and crevice corrosion resistance tests were carried out. Design/methodology/approach: The corrosion tests were realized by recording of anodic polarization curves with the use of the potentiodynamic method. The VoltaLab(R) PGP 201 system for electrochemical tests was applied. The tests were carried out in electrolyte simulating urine (pH = 5.6-6.4) at temperature of 37 plmin 1 degree centigrade. Findings: Surface condition of metallic biomaterial determines its corrosion resistance. Research limitations/implications: The obtained results are the basis for the optimization of physicochemical properties of the Ni-Ti alloy. Practical implications: On the basis of the obtained results it can be stated that Ni-Ti alloy can be applied in urology. Originality/value: The paper presents the influence of the surface treatment on corrosion resistance of Ni-Ti alloy.
