This book was released on 1971 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of applied electrical potentials on the mechanisms of hot corrosion have been studied in a potassium sulfate seeded propane/air flame at temperatures of about 1200C. Experiments were carried out with Chromel A (Ni - 20 Cr), Nickel, molybdenum, and tungsten at potentials of 250V D.C. Currents were of the order of milliamps. Both the nature of the corrosion reactions and the rates were found to be functions of electrode polarity. Electron microbe analysis of the Chromel A samples indicated enhanced sulfidation at the anode and enhanced oxidation at the cathode. Alkali metal ions seemed to be strongly attracted to the cathode and repelled from the anode. Experiments up to 1000 volts with Chromel A showed decreased net corrosion at both electrodes. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of an electric field on the oxidation of interconnect alloys was examined with a representative array of materials: an iron-base ferritic chromia former (E-brite), an iron-base ferritic chromia former with Mn and La (Crofer 22APU), a nickel-base chromia former (IN-718), and a nickelbase chromia former with Mn and La (Haynes 230). Environmental variables include temperature and oxygen partial pressure. The resulting scales were examined to determine if applied electrical current induces changes in mechanism or scale growth kinetics.

Book excerpt: This paper reviews the various types of oxidation processes occurring with pure metals and gives explanations for the varying time-temperature-oxidation rate relations that exist for copper, tungsten, zinc, cadmium, and tantalum. The effect of shape and crystal structure on oxidation is discussed. Principles derived are applied to the oxidation of alloys.

This book was released on 2004-03-11 with total page 1658 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a translation and revision of the Original Russian version by Baryahktar. It covers all of the main fields involved in Condensed Matter Physics, such as crystallography, electrical properties, fluids, magnetism, material properties, optics, radiation, semiconductors, and superconductivity, as well as highlights of important related subjects such as quantum mechanics, spectroscopy, and statistical mechanics. Both theoretical and experimental aspects of condensed matter are covered in detail. The entries range from very short paragraphs on topics where definitions are needed, such as Bloch's law, clathrate compound, donor, domain, Kondo lattice, mean free path, and Wigner crystal, to long discussions of more general or more comprehensive topics such as antiferromagnetism, crystal lattice dynamics, dislocations, Fermi surface, Josephson effect, luminescence, magnetic films, phase transitions and semiconductors. The main theoretical approaches to Condensed Matter Physics are explained. There are several long tables on, for example, Bravais lattices, characteristics of magnetic materials, units of physical quantities, symmetry groups. The properties of the main elements of the periodic table are given. Numerous entries not covered by standard Solid State Physics texts o Self-similarity o The adiabatic approximation o Bistability Emphasis on materials not discussed in standard texts o Activated carborn o Austenite o Bainite o Calamitics o Carbine o Delat phase o Discotics o Gunier-Preston zones o Heterodesmic structures o Heusler Alloys o Stress and strain deviators o Vicalloy · Each entry is fully cross-referenced to help tracking down all aspects of a topic under investigation Highly illustrated to clarify many concepts

Download or read book The Effect of a Static Electric Field on the Oxidation of Certain Metals written by G. William Lawless and published by . This book was released on 1966 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of an externally impressed, static electric field on the oxidation behavior of nickel, type 304 stainless steel, and molybdenum were investigated. While no effect was found for nickel, the oxidation rates of the stainless steel and molybdenum were markedly suppressed by the electric field within the range of field strengths investigated. Significantly, the suppressive effect was found to occur regardless of the direction of the electric field. In general, the theory of K. Hauffe on the Effect of Electric Field on the Oxidation of Metals was supported by the experimental results. (Author).
