Anodizing Layer Irregularities

Anodizing defects contamination, it arises differently on aluminum than steel surfaces. Aluminum oxide layers trap impurities unevenly, forming patchy clusters and thus complicating laser cleaning. Steel shows denser buildup, where contaminants embed deeply and resist ablation.

Formation patterns reveal unique streaks from electrolyte residues, especially after immersion. This contamination still persists in pores, so laser pulses must target precisely to avoid substrate damage.

Removal challenges intensify on porous anodized films; heat from lasers causes cracking if intensity mismatches. Material behaviors vary—aluminum responds with rapid vaporization, while alloys demand adjusted wavelengths for effective detachment. Treatment applies, surface already exhibits cleaner profiles, yet traces linger in crevices. Process yields improved adhesion, and cleaning enhances durability.
