Engine Coolant Scale

Coolant-scale-contamination forms through thermal deposition. Scale builds on surfaces during coolant exposure, so layers adhere tightly. Before cleaning, contamination exhibits irregular patterns like crystalline buildup. In laser applications, removal challenges arise because heat intensifies bonding. On metals, it resists ablation and causes surface cracking. Treatment applies pulses, yet residue persists on alloys. After exposure, patterns vary by material, so selective wavelengths help. Process demands careful control to avoid damage. Results show uneven removal on substrates.
