Special Issue Information

Dear Colleagues,

During the service operation, any metallic component will face a specific environment. This interaction can limit its lifetime or alter its properties to the point that it cannot longer satisfy the requirements. The protection of the surface of metallic materials against the environment is, therefore, of primary importance. Surface modification through chemical treatment and morphology transformation, or the deposition of the protective coating of a different material, are successful strategies to help materials resist damage and endure in harsh environments, add new biocompatible and antimicrobial functionalities, create systems for sustainable energy generation, and clean up pollutants. Currently, both academia and industry worldwide are devoting considerable research efforts to find novel surface modification techniques, coating manufacturing, or coating systems for an ever-growing range of challenges. This Special Issue, “Surface Modification and Coatings of Metallic Materials”, is dedicated to the latest scientific achievements in the field. Both reviews and articles are welcome, together with technical notes. This issue welcomes contributions of any kind in the fields of manufacturing processes of coating, such as physical and chemical vapor deposition, thermal and plasma spraying, surface modification by directed energy, electro and chemical treatments, and the properties and performance of engineered surfaces, like friction, wear and corrosion resistance, thermal protection, hydrophobic and oleophobic materials, functionalization for the environment, and energy and medical applications. All approaches will be encouraged, including theoretical, experimental, and numerical ones.

It is our pleasure to invite you to submit a manuscript for this Special Issue.

The wettability of metal surfaces by different oils and water is a multifaceted phenomenon with significant implications for industrial processes, including lubrication, corrosion protection, and fluid transport; an understanding of the process is essential for optimizing the performance and durability of metallic components. The intermolecular interactions between oil molecules and the metal surface primarily influence the wetting of a metal surface by different types of oil. This paper introduces the concept of oil wetting on metal surfaces, exploring the factors influencing wetting behavior, the characterization techniques employed to assess wetting properties, and the implications for different industrial processes. This work aims to ascertain the contact angle of oil on various metal surfaces and subsequently establish a relationship between this contact angle and the attributes of the substrate. This is achieved through using the sessile drop technique. The results indicate that the wettability of petroleum was better than the hydraulic oil we used on all types of substrates (for example, on Ag surface, Θ-petroleum = 11°, but Θ-hydraulic oil = 20°). Also, we observed that the cosine of the oil/metal contact angle increases with the increase in the atomic radius of the pure metal substrate, and Becker’s broken bond model proved this linear relation. We then contrast this behavior with the wetting characteristics of water and glycerin on the same metals using the same conditions. Full article
