Chromium Oxide Pitting

Chrome pitting contamination forms during exposure to oxidative environments on chrome surfaces, where localized pits develop irregularly and trap debris inside. After this, contamination builds up in those pits, so laser cleaning must target the spots precisely to avoid spreading damage. Pits exhibit unique clustered patterns on chrome, unlike smooth oxidation on other metals, and removal challenges arise because laser energy can deepen pits if not controlled. On chrome plating, behavior stays adherent yet brittle, so process applies pulsed beams for effective detachment without base material harm. Results indicate cleaner surfaces after treatment.
