Rust / Iron Oxide Formation

Rust forms through oxidation on metal surfaces exposed to moisture and air. Layer develops unevenly, so patterns appear patchy in humid regions. Before cleaning, contamination adheres tightly to base material. Laser treatment targets this buildup, but challenges arise from irregular thickness. Heat from beam vaporizes oxide quickly on iron, yet aluminum shows slower response because of denser layer. Removal achieves clean surface, and so process prevents further corrosion. In observations, material-specific behavior influences efficiency—steel cleans effectively during short pulses, while copper requires careful control to avoid residue. After ablation, uniformity exhibits on treated areas.
