With proper technique and proactive maintenance, metal corrosion is manageable. However, identifying different types of corrosion is crucial when determining the right preventative measure to use. Corrosion control can take on a number of forms depending on environmental conditions. According to our experts at Fourier System Nig Ltd, the surest way to prevent this mode of deterioration, maximize resources, and avoid costly damages is to detect it early on. Here, i will discuss the top three methods of corrosion control.
Top 3 Corrosion Control Methods1. Galvanic Corrosion & Sacrificial System Galvanic corrosion is most common for metals exposed to seawater or damp soil. The process occurs when different metals are in an environment with corrosive electrolytes. To fix this, galvanic anodes must be introduced into the environment to polarize the cathodes and stop corrosion in its tracks. In the “sacrificial system,” the added metal anodes corrode themselves to prevent the original structure from deteriorating. The most common types of metal used in this process are zinc and aluminum. 2. Plating In plating, a metallic coating is applied to prevent corrosion from progressing. This is the most commonly used method because it’s both quick and aesthetically pleasing. In electroplating, steel and other substrate metals are given an electrolytic bath made from a water-based solution and metallic salts. The process leaves a thin coating of zinc, nickel, or chromium to protect the metal from corrosion. 3. Painting & Organic Coating Painting over metal delays the rusting process and protects it from harsh environmental gasses. The kind of paint or coating used depends on the environmental elements the metal structure is exposed to. Certain types of protective coating may also provide reinforcement to the structure.
