Steel Surface Corrosion

Steel corrosion contamination, it forms through oxidation exposure. Iron in steel reacts with oxygen and moisture, thus creates rust layers. These layers exhibit unique patterns, such as pitting on surfaces and flaky buildup in humid regions. Formation follows environmental factors, and natural regional patterns influence thickness variation.

Removal in laser cleaning applications, it presents distinct challenges. Contamination adheres strongly to substrate, so laser energy must balance ablation without damaging base material. Steel's thermal conductivity affects process, thus requires precise pulse control. After treatment, residues sometimes persist on uneven areas, and this demands multiple passes. Method removes oxide effectively, yet heat accumulation risks further corrosion if not managed. Surface uniformity improves following adjustment, and cleaning enhances durability overall.
