he global corrosion protection coatings market size is projected to grow from USD 6.9 billion in 2020 to USD 8.9 billion by 2025, at a CAGR of 5.3%.The global corrosion protection coatings market is growing due to the end-use industries such as marine, oil & gas, petrochemical, infrastructure, power generation, and water treatment. Hence, the rapid growth of these industries is expected to contribute to the growth of the corrosion protection coatings market. However, the market is expected to decline in 2020 due to the global COVID-19 pandemic.

"Formation of a surface layer, whether it is based on an oxide, carbonate, sulfate, or any other compound, is a major factor in corrosion resistance, particularly if the layer effectively isolates the metal substratum from the environment. Such a naturally formed coating must be diffusion- and moisture-resistant to be effective. Ordinary iron does not naturally form an effective barrier; its rust permits oxygen and moisture to penetrate and continue rusting. Thus, unless precautions are taken, such as applying a protective coating over the surface, failure will eventually occur."

"Arcadia program will work with nature to develop "probiotics" for military materials and equipment to prevent corrosion, decrease drag.(...) Bacteria are the most abundant and diverse lifeform on Earth, coating almost every surface, with the majority spending their lives in biofilms.his lifestyle is universally perceived as problematic since biofilms contribute significantly to equipment degradation. However, biofilms do not have to be a problem. New insights suggest biofilms could be rendered beneficial by redirecting their composition and structure. Similar to the Arcadian vision of harmony with nature, the DARPA Arcadia program will develop "probiotics" to protect military materials and equipment using naturally occurring microorganisms to generate robust and beneficial coatings."

The global impacts of corrosion are significant and far-reaching, and until recently, so were the negative effects of anti-corrosion coatings on our environment as well as human health and safety. Innovative eco-friendly additives should be good news for economies, industry and ecosystems.

"Corrosion has a huge economic, environmental and sustainability impact on virtually all facets of constructional materials, from highways, bridges, and buildings to oil and gas, chemical processing, desalination, nuclear, power facilities, water, and wastewater systems. In addition to causing severe environmental damage and threats to public safety, corrosion disrupts operations and requires extensive repair and replacement of failed assets. The annual cost of corrosion worldwide was estimated to exceed $U.S.2.5 trillion in 2016, which translates to 3 to 4% of the Gross Domestic Product (GDP) of industrialized countries according to NACE IMPACT study report. (...) To reduce the huge cost and the environmental impact of corrosion and enhance the sustainability of materials used for construction, available corrosion control practices such as proper material design and selection, the use of corrosion inhibitors, coatings, cathodic protection etc., are recommended and could lead to savings of between 15 and 35% of the cost of corrosion. This translates to between US$375 and $875 billion annually"

"The aim of this paper is to describe the factors within a tunnel environment that may contribute toward a corrosive atmosphere, and considering these, to determine the corrosivity of the atmosphere throughout a tunnel environment and present methods to mitigate against corrosive damage."

Corrosion is a huge cost to the environment. These range from structural failures resulting in environmental contamination, to harmful pollutants being released from iron corrosion, to the over-utilization of natural resources when repairing and replacing damaged metals (Hanson, 2011).(....)the longevity of the metal assets in question across key industries such as O&G, aerospace and architecture is one of the largest drivers for innovation in the coatings industry.
