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.

Over the past four decades, there has been increased attention given to the research of fluid mechanics due to its wide application in industry and phycology. Major advances in the modeling of key topics such Newtonian and non-Newtonian fluids and thin film flows have been made and finally published in the Special Issue of coatings. This is an attempt to edit the Special Issue into a book. Although this book is not a formal textbook, it will definitely be useful for university teachers, research students, industrial researchers and in overcoming the difficulties occurring in the said topic, while dealing with the nonlinear governing equations. For such types of equations, it is often more difficult to find an analytical solution or even a numerical one. This book has successfully handled this challenging job with the latest techniques. In addition, the findings of the simulation are logically realistic and meet the standard of sufficient scientific value.

Plasma electrolytic oxidation (PEO) is a surface treatment for the production of ceramic oxide coatings with great properties, such as high wear and corrosion resistance, on metal substrates, particularly aluminum and magnesium alloys. Formation of PEO coatings involves complex processes and mechanisms that are difficult to study. Currently, the PEO process is in a transition phase from research to commercial application, with a primary focus on the corrosion and wear protection of light alloys, and has recently generated interest as a promising surface treatment for biomedical applications. To justify the industrial application of PEO, a more systematic and in-depth study of the influence of various parameters on the process is required. The control of the PEO process to yield the desired morphology and microstructure for specific applications is a key requirement if the process is to be industrially applied. The aim of the research in this thesis is to study the influence of electrical parameters, so they can be optimized to produce coatings with enhanced properties mainly for tribological applications. Alumina coatings were deposited on 6061 aluminum alloy substrates in an alkaline silicate electrolyte using a unipolar pulsed DC current mode. The influence of processing conditions, mainly electrical parameters (applied frequency, duty cycle, and current density), on the formation, growth behaviour and properties of PEO coatings were investigated. Different characterization methods including scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffractometry, microhardness testing, electrochemical impedance spectroscopy, and linear polarization resistance measurements were used to study the microstructure, morphology and properties of the coatings. The correlation between the stage of the PEO process and the properties of the coating has been shown. The voltage-time response was found to be important since it provided readily measurable and useful information about these stages. It was found that the microstructure, morphology, growth rate, phase distribution and composition of coatings could be changed by varying the electrical parameters. To some degree corrosion performance could be tailored by adjusting processing parameters.

Plasma electrolytic oxidation (PEO), a novel method for forming ceramic coatings on metals, has been researched extensively in recent times. By applying high voltage between dielectric thin films, a plasma micro-arc is induced through penetration of breakdown in film boiling layer. Such a method takes advantage of high processing time, low equipment requirement and advanced coating performance.Titanium alloys, Ti-6Al-4V and pure Titanium Grade 2, are two of most common Titanium alloys in daily use. Both of such Titanium alloys show great potential utilization in bio-medicinal application, especially in implants, for its excellent biocompatibility, high tensile strength, and high elastic modulus. However, in vivo environment is hazardous for metals and alloys. The body fluid is corrosive for metallic implants even for the chemically stable Titanium alloys. Thus methods have been used for surface modification and coating. Plasma electrolytic oxidation has shown its advantage on such demands.In this thesis, the in vitro corrosion experiment is done on the PEO treated Titanium alloys .The potential of PEO treated metals has few tests in vitro before for bio-medicinal usage. And also the potential dental and implants utilization of PEO treated Titanium alloys can be fulfilled by such analysis and qualified for in vivo test. The surface morphology is analyzed by various of methods in microscopy, electrochemical methods and XRD.

This book offers readers a valuable overview of recent advances in biomedical engineering, as applied to the modern dentistry. It begins by studying the biomaterials in dentistry, and materials used intraoperatively during oral and maxillofacial surgery procedures. Next, it considers the subjects in which biomedical engineers can be influential, such as 3-dimensional (3D) imaging, laser and photobiomodulation, surface modification of dental implants, and bioreactors. Hard and soft tissue engineerings in dentistry are discussed, and some specific and essential methods such as 3D-printing are elaborated. Presenting particular clinical functions of regenerative dentistry and tissue engineering in treatment of oral and maxillofacial soft tissues is the subject of a separate chapter. Challenges in the rehabilitation handling of large and localized oral and maxillofacial defects is a severe issue in dentistry, which are considered to understand how bioengineers help with treatment methods in this regard. Recent advances in nanodentistry is discussed followed by a chapter on the applications of stem cell-encapsulated hydrogel in dentistry.Periodontal regeneration is a challenging issue in dentistry, and thus, is going to be considered separately to understand the efforts and achievements of tissue engineers in this matter. Oral mucosa grafting is a practical approach in engineering and treatment of tissues in ophthalmology, which is the subject of another chapter. Microfluidic approaches became more popular in biomedical engineering during the last decade; hence, one chapter focuses on the advanced topic of microfluidics technologies using oral factors as saliva-based studies. Injectable gels in endodontics is a new theme in dentistry that bioengineering skills can advance its development, specifically by producing clinically safe and effective gels with regeneration and antibacterial properties. Engineered products often need to be tested in vivo before being clinical in dentistry; thus, one chapter is dedicated to reviewing applicable animal models in dental research. The last chapter covers the progress on the whole tooth bioengineering as a valuable and ultimate goal of many dental researchers. Offers readers an interdisciplinary approach that relates biomedical engineering and restorative dentistry Discusses recent technological achievements in engineering with applications in dentistry Provides useful tool to dental companies for future product planning, specifically to biomedical engineers engaged in dental research
