The hazards of coating failure must be taken seriously
Thread Content
Even if only a small area of the coating fails, it can lead to corrosion, damaging the overall structure and ultimately causing failure. Coating failures such as corrosion, degradation, and coating peeling can result in high repair costs and extended downtime; engineers and chemists need to investigate the causes of these failures in order to avoid potential additional costs. Coating-related failure issues are highly complex, which makes it difficult to determine the root causes of such failures, especially when these causes include both mechanical and environmental factors. It is crucial to assess the main causes of coating failure in order to weigh economic responsibilities and understand the underlying reasons for such failures. Therefore, it is highly necessary to have a thorough understanding of the common types of coating failures, their causes, and potential remedial measures.
Even a small area of the coating to fail can lead to corrosion. A typical example is the substandard quality of the nano-anti-corrosion steel heat exchange tube bundles: bubbling occurred in the coating on the circulating water side, and within a week the tube bundles suffered from perforation and corrosion, rendering them unusable
