Passivation Layer Irregularities

Passivation-defect-contamination arises on metal surfaces. It forms through oxide layer disruptions and defect sites. This contamination, it shows unique regional patterns, clustered in natural zones. Formation follows exposure to air and residues, thus builds uneven coatings.

Removal challenges emerge in laser cleaning. Defects resist ablation, and contamination clings tightly. Material-specific behaviors vary: on steels, it disperses slowly; on aluminums, it scatters more readily. Treatment applies laser pulses, so surface cleans progressively. Challenges persist, yet efficiency improves with targeted adjustments. This contamination still demands precise control for complete removal.
