Full Description
This volume provides the fundamentals and most recent information on Plasma Electrolytic Oxidation (PEO) in one authoritative resource. The authors explain how PEO has attracted significant research attention in the last decade as a potential industrial method for surface engineering of metals and alloys in various application domains. It further documents their advantages in producing thicker and more effective coatings over conventional industrial anodization processes and that PEO coatings can be used as anticorrosion and anti-wear coatings, thermal barrier layers and catalytic layers. The book is divided into four sections addressing fundamentals, growth mechanisms, effects of particles, and industrial applications. Promoting maximum understanding of the fundamentals of the PEO process as essential to developing more competitive surface technologies, the book is ideal for a range of engineers and fabricators working in metals and alloys, surface modification, corrosion, electrochemistry, materials chemistry, and nanotechnology.
