Preventing corrosion and all types of wear—particularly corrosion-induced wear at varying temperatures—is a key challenge here. HVOF spraying, suitable for on-site applications, is widely utilized to combat corrosion, abrasion, and erosion, especially with carbide-based cermets. External steel structures, pipes, and tanks often receive aluminum, zinc, or zincaluminum coatings applied via wire arc or flame spray, alongside polymer coatings applied by flame, HVOF, or plasma depending on melting points. Thermal spray technologies coat many components in the oil, gas, and petrochemical sectors.
