摘要

In this work, we investigate surface oxidation on AISI 304 stainless steel using a low-cost engraving system based on a 445 nm diode laser. The treated samples were analyzed by optical microscopy and by Raman spectroscopy. The oxides formed on the steel surface were identified, and the results showed the influence of the operating parameters on the oxidation formation process.
