Corrosion and Protection of Metallic Materials, 2nd Edition

Dear Colleagues,

Following a previous Topic (“Corrosion and Protection of Metallic Materials”; https://www.mdpi.com/topics/corrosion_protection_metallic_materials), this new Topic is a collection of research contributions that explore the latest developments in the fields of both surface science and engineering in the areas of corrosion and degradation phenomena, and the most suitable procedures to protect the metallic materials.

Corrosion is the process of degradation or the failure of metallic materials in contact with the surrounding environment. Nowadays, the corrosion of metallic materials remains a technological and major economical challenge because the service lifetime of materials containing metallic components is often limited by the stability or durability of their metallic parts. The environmentally assisted degradation of metals and alloys in civil engineering structures has a detrimental effect on their mechanical and physical properties; this may lead to the collapse of infrastructure, such as the Morandi bridge in Genoa on 14 August 2018, which caused the death of 43 people, the corrosion of stainless steel tanks, such as the Bhopal gas disaster in India in 1984, or lead to environmental consequences, such as the Prestige Oil Spill in Galicia in 2002. The economic impact of metallic corrosion and protection is generally estimated to be about 4.9% of gross domestic product in well-developed countries. One estimate suggests that 40% of this cost could be easily saved with a superior understanding of the basic concepts of protection and material selection. On the other hand, ecological aspects are becoming increasingly crucial, e.g., environmental protocols that seek to reduce fuel consumption and the emission of greenhouse gases. For example, between all the metallic materials utilized for structural applications, magnesium (Mg) alloys have the lowest density; however, their low resistance to corrosion and wear remains one of the main limitations in the use of Mg alloys for transportation applications.
