WebFurthermore, chromium plating desires to achieve a good as possible corrosion resistance. An improvement regarding corrosion resistance is known in the art. For example, CN 102703899 A relates to a surface treatment process for a cylinder including laser cladding and subsequent chromium deposition. WebJun 30, 2024 · When under corrosive attack, the hexavalent chromium undergoes active corrosion protection and reduces to form trivalent chromium. The insoluble trivalent chromium can then end the attack. Though, lead and chromate pigments have excellent corrosion resistance, but they are highly toxic in nature.
