About this Research Topic
Corrosion is a worldwide important problem that strongly affects the performance and integrity of metallic alloys in industrial environments. In recent years, technical reports have estimated that global corrosion direct costs are around 3.5% GDP, and it has also been mentioned that a significant percentage can be saved through appropriate control methods oriented to help preventing damage to process equipment and the environment, and increasing people’s safety. Equipment and process lines in industries such as chemical, food, oil, petrochemical, aeronautics, nuclear etc., are built from metallic alloys, mainly carbon steels, low alloy steels, stainless steels, and special alloys. The operating conditions of these materials can be very different and some important factors such as the chemistry of the environment, temperature, pressure, and flow conditions can cause corrosion damage.
Different corrosion engineering control methods are reported in the literature to prevent metallic surface deterioration. Among these methods, without any doubt the use of coating systems is the most used and important. In recent years, research groups throughout the world have been working on advancements related to the development and testing of novel coatings systems for ferrous and non-ferrous alloys with improved chemical and mechanical properties. Novel organic and inorganic coatings reinforced with metallic and ceramic nano-particles, organic–inorganic hybrid sol–gel coatings, inorganic zinc treatments, metallic composite coatings, electro and electroless processes, and thin and thick films (Cermet’s) for aggressive environments are under development and testing. In addition, environmental issues demand more research on environmentally friendly corrosion protective systems such as green corrosion inhibitors and novel passivation processes.
The aim of this Research Topic is to present the latest developments on advanced coating technologies and trends for corrosion protection of metallic alloys. This is a multi-disciplinary area and thus, covers a wide range of applications in the field of corrosion protection. We invite researchers to submit theoretical and experimental original research articles, as well as mini and full reviews related to (but not limited to) the following research topics:
• Organic and inorganic coatings
• Conversion coatings
• Sol-gel coatings
• PVD and CVD coatings
• Electro and electroless plating
• Spray coatings (thermal/cold spray)
• Environmentally friendly inhibitors and passivation processes
• Composite and powder coatings
• Self-healing coatings
• Characterization of mechanical and electrochemical behaviour
• Laboratory testing and field evaluation
