Preface

Ceramic Coating is a protective thin film for all kinds of parts and can dramatically increase their useful life, and therefore, productivity increases by reducing maintenance downtime and by achieving longer run times before repairs are needed. Ceramic coatings are inorganic, non-metallic solid and inert thin films made by deposition, heating and subsequent cooling, which may be crystalline. That is, the definition of ceramic coatings is often restricted to inorganic crystalline thin films. About the fabrication of ceramic coatings, the main methods are physical deposition (like magnetron sputtering deposition and plasma spraying process) and chemical deposition, such as electrochemical deposition, which can affect the microstructures and properties of the ceramic coatings.

In order to know more about the ceramic coatings in the past several years, this book is organized by Intech open access publisher and wroten by different authors, who are focused on the modern ceramic coatings—applied in engneering. A feature of this text is that we keep in mind that many of today's high-tech ceramic coatings and processing routes have their origin in the microstructures and properties. Throughout the text we will make connections to these related fields. The text covers ceramic coatings from the fundamentals to industrial applications including a consideration of safety and their impact on the modern technologies, including EPD-process, physical deposition process, applications in engineering, pigment and foundry.

At last, we thank all the authors and all the editors who contribute greatly to this book and we hope that every readers are interested in this book.

It is easy to prepare TiO2 film by electrochemical deposition method technologically. There are some other electrodeposition methods, such as electrophoresis method, anodic-

Tan Xiaochun[1] et al. set up a film formation model by electrophoresis method based on experiments and made an exposition of electrophoresis mechanism. The results showed that colloidal concentration and size, DC bias and time are the major factors to form a film.

Nanometer TiO2 film prepared by cathodic-electrodeposition is formed in the form of microcrystalline piling up. Kavan[3] et al. took TiCl2 solution as an electrolyte, to get amorphous Titanium (IV) hydrate film on the anode, and the TiO2 film after heat treatment. Cui Xiaoli[4] et al. prepared TiO2 film on the ITO glass substrate with anodicelectrodeposition method, and investigated the effect of the anodic current and deposition

Natarajam[5] et al. used Titanium powder as a raw material, which was dissolved with H2O2 and NH3 to get colloid, so that can accomplish the cathodic-electrodeposition on ITO glass in the aqueous solution. Karuppuchamy[6] et al. took TiOSO4 as a raw material, to prepare TiO2 film by cathodic-electrodeposition, the SEM testing results showed that the TiO2 film is of porous. When a electrode was photosensitized with dyestuff, the incident light current

Most of cathodic-deposition are accomplished on ITO glass. Chi-Min Lin[7] et al. took TiCl4 ethylbenzene as an electrolyte, and accomplished the cathodic-electrodeposition on pure Ti. But there are few reports on the study of cathodic-electrodeposition on TiNi SMA. In this experiment, a self-prepared aqueous solution of Ti(SO4)2 was taken as the electrolyte, the cathodic-electrodeposition of TiO2 film on TiNi SMA was achieved. This method is with more convenient in operation, lower cost and easier to accomplish
