Purpose: The work presents the influence of artificial urine environment and surface treatment of Co-Cr-W-Ni alloy, intended for implants applied in urogenital surgery, on their corrosion resistance. The tests were carried out in three artificial urine solutions that differed in chemical composition at the temperature 37±1*C 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® PGP 201 system for electrochemical tests was applied. The tests were carried out in electrolyte simulating urine (pH=5.6-6.4) at the temperature of 37±1*C. Findings: The obtained results indicate diverse corrosion resistance of the Co-Cr-W-Ni alloy depending on the applied surface treatment and chemical composition of the artificial urine that can be connected with individual reactivity of patients. Research limitations/implications: The obtained results are the basis for optimization of physicochemical properties of the Co-Cr-W-Ni alloy and allow to select only one artificial urine solution for further corrosion tests. Practical implications: On the basis of the obtained results it can be stated that Co-Cr-W-Ni alloy can be applied in urology. Originality/value: The paper presents the influence of artificial urine environment and the surface treatment on corrosion resistance of Co-Cr-W-Ni alloy.
