Purpose: The paper presents physicochemical properties and biomechanical analysis of fixation plates made of Cr-Ni-Mo stainless steel used in the funnel chest treatment. 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 numerical analysis was performed for: the stabilizer of 460 mm length, 16 mm width and 4.5 mm thickness, the stabilizer of 460 mm length, 16 mm width and 3.5 mm thickness, the stabilizer of 460 mm length, 16 mm width and 2.5 mm thickness. Findings: The tests showed that structure of the steel the plates were made of, met the PN-ISO 5832-1 standard. The surface damage is induced in the given deformation regions and is a potential reason of corrosion. The numerical analysis shows that stresses in plates didn’t exceed the yield point: for the stainless steel Rp0,2min = 590 MPa. Values of maximum displacements occuring in the stabilizing bar in the range of clinically acceptable displacements. Research limitations/implications: The obtained results are the basis for the optimization of physicochemical and mechanical properties of the metallic biomaterial. Practical implications: On the basis of the obtained results it can be stated that that stainless steel can be applied in the funnel chest treatment. Originality/value: The paper presents the influence of surface damage and stresses and displacement of plates used in the funnel chest treatment on the corrosion resistance.
