What are the most common issues with the durability of metal components in salty air?
Metal components exposed to salty air often face severe durability challenges due to the corrosive nature of salt. The most common issues include:
1. Accelerated Corrosion – Saltwater accelerates oxidation, leading to rust and structural weakening, especially in iron and steel.
2. Pitting Corrosion – Chlorides in salt create localized pits on metal surfaces, compromising integrity over time.
3. Galvanic Corrosion – When dissimilar metals are in contact, salt acts as an electrolyte, speeding up electrochemical degradation.
4. Stress Corrosion Cracking – Combined salt exposure and mechanical stress can cause sudden fractures in susceptible alloys.
5. Coating Degradation – Protective layers like paint or zinc coatings break down faster, leaving metal vulnerable.
To mitigate these issues, manufacturers use corrosion-resistant alloys, protective coatings, and regular maintenance. Understanding these challenges helps in selecting the right materials and preventive measures for coastal or marine environments.
