The paper presents the surface structure formation of AISI 304 stainless steel using the MiniMarker2-20A4 laser system. Austenitic steel was in the form of a cold-rolled sheet and a tape of increased strength for parts and structures. The article reviews the corrosion-resistant steel surface condition after analyzing the influence of power, frequency and speed of the laser and evaluates the impact on the corrosion resistance of the treated surface. The contrast assessment shows the treated structure effect on the alloy surface reflectivity. The calculations of the most optimal marking are made for obtaining the greatest contrast. The maximum contrast obtained as a result of parameter optimization was 0.83 and was improved by 10%. The article also touches on the influence and susceptibility to corrosion of stainless steel samples with laser marking by QR codes. This point displays structural change of the processed area and presentations steel surface structure AISI 304 after corrosion tests.

Laser marking is a universal method of applying information to the products surface. Colored oxide films form on metal surface during a thermal exposure. The degree of steel heating influences the film thickness. Corrosion-resistant steel AISI 304 samples were laser-marked with a MiniMarker 2-20A4 precision laser complex. The contrast of the barcodes on a metal area depends on the surface roughness and the chemical composition of the steel. Fe2O3, Fe3O4 oxides forms the greatest contrast. RGB indicators are used to assess contrast. Study results may be applicable to increase the QR code contrast thereby contributing to the improvement of laser marking technology while preserving economic efficiency.
