Available in PDF, EPUB and Kindle. Book excerpt: Electroplating as a surface treatment technology can significantly improve the properties of working parts and components which has been widely applied in a variety of technical fields. Recently this surface treatment technology has been developed to synthesize nanocomposite coatings. The nanocomposite coatings show a significantly improved mechanical properties due to the second-phase dispersed nanoparticles in the coating matrix. However, it is hard to realize a good suspension of solid nano-sized particles in a plating solution and good dispersion of nano-sized particles in the composite coatings because of the large surface energy of nano-particles. The traditional methods such as magnetic agitation, air injection, and ultrasonic vibration are always difficult to fully prevent agglomeration of nano-sized particles as the surface effect. To achieve a good dispersion of the nanoparticles in composite coatings, sol-gel enhanced electroplating is developed at the University of Auckland and intensively investigated. The aim of this research is to study the electroplating of sol enhanced Ag/TiO2 composite coatings. In the present thesis, TiO2 solid particles and a transparent TiO2 sol was added into a traditional cyanide silver electroplating electrolyte in order to prepare two different types of composite coatings. The research was started with an electroplating of pure silver coatings from traditional cyanide bath. Then investigations were carried out on the solid powder enhanced composite coatings and sol-enhanced composite coatings focused on the effect of the powder and sol concentration. The microstructure, mechanical properties, electrical properties as well as colour difference of the composite coating were investigated in the research. Both of the sol and powder enhanced electroplating successfully added dispersed TiO2 nanoparticles into the Ag coating matrix and improved the mechanical properties compared to the pure silver coating. The sol enhanced nanocomposite coatings shows better dispersion and mechanical properties.

Available in PDF, EPUB and Kindle. Book excerpt: Nano-composite coatings have wide applications for their superior mechanical and corrosion properties. Many efforts have been devoted to the development of different types of nano-composite coatings in the last decade. Various techniques are used to modify the coating microstructure at the nano scale in order to further improve the properties of coatings. We recently developed a novel method which combines sol-gel process and electrochemical deposition process to produce nano-composite coatings. This simple method can lead to a highly dispersed distribution of oxide nano-particles in the metal coating matrix, resulting in significantly improved mechanical properties. This Chapter introduces the principle of this innovative method, the basic theory behind the deposition process, and an overview of current results. It also describes the dopant technology that is derived from this novel technique. The future development potentials and industrial applications of these coatings are also discussed.

Download or read book Chemical Solution Deposition of Functional Oxide Thin Films written by Theodor Schneller and published by Springer Science & Business Media. This book was released on 2014-01-24 with total page 801 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first text to cover all aspects of solution processed functional oxide thin-films. Chemical Solution Deposition (CSD) comprises all solution based thin- film deposition techniques, which involve chemical reactions of precursors during the formation of the oxide films, i. e. sol-gel type routes, metallo-organic decomposition routes, hybrid routes, etc. While the development of sol-gel type processes for optical coatings on glass by silicon dioxide and titanium dioxide dates from the mid-20th century, the first CSD derived electronic oxide thin films, such as lead zirconate titanate, were prepared in the 1980’s. Since then CSD has emerged as a highly flexible and cost-effective technique for the fabrication of a very wide variety of functional oxide thin films. Application areas include, for example, integrated dielectric capacitors, ferroelectric random access memories, pyroelectric infrared detectors, piezoelectric micro-electromechanical systems, antireflective coatings, optical filters, conducting-, transparent conducting-, and superconducting layers, luminescent coatings, gas sensors, thin film solid-oxide fuel cells, and photoelectrocatalytic solar cells. In the appendix detailed “cooking recipes” for selected material systems are offered.
