Why are aluminum outdoor chairs prone to electrolytic corrosion in marine environments?
Aluminum outdoor chairs are highly susceptible to electrolytic corrosion in marine environments due to prolonged exposure to saltwater and humidity. Saltwater acts as an electrolyte, accelerating the electrochemical reaction between aluminum and other metals, leading to oxidation and pitting. Additionally, the high chloride content in seawater breaks down aluminum's protective oxide layer, making it vulnerable to further degradation. To mitigate this, choosing corrosion-resistant alloys or applying protective coatings can significantly extend the lifespan of aluminum furniture in coastal areas. Regular maintenance, such as rinsing with fresh water, also helps reduce salt buildup and corrosion risks.
