Abstract

The paper presents research on fractal analysis of martensitic steel X39Cr13 used for the manufacturing of surgical instruments. Fractal analysis was performed on samples subjected to sequential processes: annealing, surface treatment and sterilization. Annealed samples were tested towards corrosion resistance in physiological solution. Fractal analysis revealed that annealed samples were bifractal, whereas the remaining ones appeared monofractal. Hence, sterilization did not affect the surface morphology of the steel. On the other hand, after corrosion tests there were regular pits several hundreds of micrometers in diameter found in the annealed specimens.

Keywords: X39Cr13 steel, fractal analysis, surface topography
