Corrosion and protection in the wave splash zone

Thread Content

In areas where waves splash, coatings tend to peel off due to the impact of seawater, and electrochemical protection cannot function effectively as a stable current circuit cannot be established. Corrosion prevention experts around the world have studied various methods to address this issue, developing highly durable anti-corrosive coatings that utilize materials such as clad Monel alloy, copper-nickel alloys, stainless steel, sacrificial steel, concrete, rubber, and fiberglass. PTC laminated petrolatum coating anti-corrosion technology is inexpensive, easy to apply, and requires minimal surface treatment. It has been in use abroad for over 35 years, while in China it has been utilized for more than 10 years. As China’s marine development in areas such as offshore oil fields and wind power continues to advance, along with the construction of more marine steel structures, it is of great economic value and social significance to develop long-term and effective corrosion protection and repair techniques for wave splash zones in different marine environments and with various structural types in China.
