Quenching Oil Residue

After quenching, oil contamination forms uneven layers on metal surfaces, because rapid cooling traps residues in pores and cracks. This buildup exhibits unique patterns, such as patchy films that harden during exposure to heat, and so removal becomes challenging in laser cleaning. Contamination adheres strongly to ferrous materials, where it penetrates deeply and resists vaporization, while on non-ferrous alloys, layer releases more easily yet leaves oily traces. During laser application, thermal damage arises so operators adjust pulses to avoid substrate harm. Process removes contamination effectively, as scans show cleaner surfaces after treatment, and results are obtained from repeated tests on samples. Surface achieves uniformity in observations.
