Water-Side Corrosion
Water-Side Corrosion is damage on the waterside of heat-exchanging components. It's caused by poor water treatment and leads to corrosion fatigue.
Physicochemical Mechanism of Action
Water jacket corrosion occurs when the water flowing through heat-exchanging components (like pipes or radiator sections) is inadequately treated. This means it contains too many contaminants or lacks proper chemical additives. These contaminants react with the metals and strip away their electrons, leading to corrosion.
Metallurgical Relevance & Welding Risks
Water jacket corrosion can cause severe depletion of the components. This means the parts lose their mechanical properties and have to be replaced sooner. This can lead to failures in radiator sections or pipes, resulting in operational disruptions and possibly serious safety issues.
Workshop Practice & Action Guidelines
To prevent water jacket corrosion, it's important to treat the water in heat-exchanging components regularly. This means removing contaminants and adding proper chemical additives. A typical process involves removing chloride ions and adding lime or other neutralizing agents. Exact values and procedures vary depending on the material used and the specific application.
