Plasma electrolytic oxidation (PEO), also known as micro-arc oxidation (MAO), functionalizes surfaces, improving the mechanical, thermal, and corrosion performance of metallic substrates, along with other tailored properties (e.g., biocompatibility, catalysis, antibacterial response, self-lubrication, etc.). The extensive field of applications of this technique ranges from structural components, in particular, in the transport sector, to more advanced fields, such as bioengineering. The present Special Issue covers the latest advances in PEO‐coated light alloys for structural (Al, Mg) and biomedical applications (Ti, Mg), with 10 research papers and 1 review from leading research groups around the world.

Recently, the scientific community has deemed surface modification to be necessary because the surface properties of new materials are usually inadequate in terms of wettability, adhesion, corrosion resistance, or even drag reduction. In order to modify solid surfaces such as metals and alloys, different treatments have been used to obtain a desired surface finish, including chemical vapor deposition, physical vapor deposition, chemical etching, electrodeposition, or the application of non-equilibrium gaseous media, especially gaseous plasma. These treatments promote changes in roughness, hydrophobicity, biocompatibility, or reactivity. Although such treatments have been studied extensively over the past decades and even commercialized, the exact mechanisms of the interaction between reactive gaseous species and solid materials are still inadequately understood. Moreover, for various reasons, it is difficult to find an alloy with a surface behavior that differs from that of the bulk. A frequent goal of surface modification is to obtain a greater or more specific resistance to extreme environments, including resistance to corrosion and wear; higher mechanical or fatigue resistance; hydrophobicity; oleophilicity; or thermal (for low or high temperature exposure), magnetic, electrical, or specific optic or light exposure behavior. Another objective is to increase biocompatibility, prevent (bio)fouling, or both. In order to achieve and improve these properties in metals and alloys, the strategy of surface modification must be applied on the basis of direct action on the metal or the incorporation of a coating that will provide these properties or functionalize its surface to meet complex requirements.

The enhancement of life and the performance of metal engineering components is mainly determined by surface characteristics. The latter has a pivotal role in enhancing the life of products since they control the mechanical, electrical, thermal, and electronic properties. Nevertheless, the surface and near-surface properties are crucial in failure mechanisms since the loss of performance and failures mostly begin from the surface. Research advances in the designing, processing, and characterizing of textured surfaces broadly support innovative industrial applications and products.The performance improvement in engineering components during operation is a challenging issue and surface engineering methods have been attracting considerable interest in both research and industrial fields. Even though many attempts have been made to face the wear of metals by tuning the physical, chemical, mechanical, and metallurgical properties of their surfaces, several important aspects need to be still deepened.The present book collects original research papers and a review that covers the latest development in methods for enhancing the life and functionality of engineering components by tuning the physical, chemical, mechanical, and metallurgical properties of their surfaces. Attention is focused on processing and characterizing methods capable of supporting industrial applications and products to both tackle surface degradation and improve the performance and reliability of components.

In recent decades, there have been extensive developments in science and technology. These advances provide new techniques to deposit coatings onto various substrates, thus, addressing the ever-increasing performance requirements of various applications. Moreover, as technology itself develops, there are new problems that require new solutions, some of which can be solved through the application of coatings. Thus, the demands from coatings are continually increasing and the field is growing. The collection of articles contained within this volume cover a wide range of different research approaches to coatings reflecting the expanding field of coatings.
