Resumo
Austenitic stainless steel ISO 5832-1 is widely used as biomaterial due to its
mechanical properties, chemical composition, degradation resistance and low
cost. In this work, we evaluated the magnetic susceptibility of samples of this
biomaterial, with laser texturing surface treatment in four different pulse
frequencies, as well as samples without laser treatment, for comparison purposes.
Relative magnetic permeability (μr) measurements were performed on a magnetic
susceptibility scale. A Bruker magnetic force microscope (MFM), model SPM
Multimode 8, with analysis processing software Nanoscope Analysis, was used in
the Tapping Mode operation to perform naturally generated magnetic field
measurements on the laser textured samples surfaces. The treatments affected
the magnetic susceptibility of these surfaces, which was higher for the textured
samples when compared to the other surface finishing conditions, which is
undesirable for a biomaterial. The magnetic field evaluations by MFM are of
qualitative character. Qualitatively distinct images of amplitude and phase
difference signals were noted. This fact proved the results obtained by the
technique of measurement of magnetic signals by precision scale. The analysis of
the images obtained by MFM suggested that the parameters variation for laser
texturing resulted in variation of intensities and distribution of magnetic field
signals on this biomaterial’s surfaces.
