Download or read book Wire Cut Electrical Discharge Machinability of Ceramics written by and published by . This book was released on 1987 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: THe wire-cut electrical discharge machinability of four ceramics was evaluated. Titanium diboride and silicon carbide workpieces were successfully cut in the monolithic state. Boron carbide could only be cut when a metallic sandwich structure was placed around the workpiece. Silicon nitride could not be successfully cut. Mechanisms of material removal as well as a minimum level of workpiece electrical conductance necessary for EDM are proposed. Characterization of the surface damage resulting from electrical discharge machining is presented. Recast, partially melted, and heat affected zones are identified. The effects of parametric processing variations on surface integrity are discussed. Flexure strength and residual stress data are compared for EDM cut and diamond ground surfaces in titanium diboride. Certain limitations are proposed for the EDM fabrication of ceramic components where surface defects are strength limiting.

This book was released on 2018-01-12 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric Discharge Machining (EDM) is very important and prominent machining process among all the newly developed non -traditional machining techniques. This process is extremely useful for “difficult to machine” conducting materials such as heat treated tool steels, composites, super alloys, heat resistant steels, ceramics, carbides, etc. In this technique i.e. in EDM, the material removal of the electrode is achieved through high frequency sparks between the tool and the work-piece immersed into the dielectric. The Material Removal Rate (MRR), Tool Wear Rate (TWR) and surface roughness are some of the important performance parameter of EDM process. The objective of EDM is to get high MRR as well as achieving reasonably good surface quality of machined component. The machining parameters that achieve the highest MRR strongly depend on the size of the machining surface i.e. Electrode used and work-piece surface. With upcoming worldwide important applications of Non-Conductive ceramics machining has become an important issue which needs to be investigated in much detail. The Alumina (Al2O3), Glass and other advanced engineering ceramics are rapidly emerging class of engineering materials possessing a wide range of remarkable properties i.e. high hardness, chemical stability, very low friction, unique electrical properties and these engineering ceramics posses high wear resistance which make them highly suitable for such engineering applications as jet engines and other aeronautical components, tools and dies and electronic sensors.

Book excerpt: The organizers of this Fifth Symposium maintained their initial objectives, namely to gather experts from both industries and universities to discuss the scientific problems involved in the preparation of heterogeneous catalysts, and to encourage as much as possible the presentation of research work on catalysts of real industrial significance. Another highlight of these symposia was to reserve a substantial part of the program to new developments in catalyst preparation, new preparation methods and new catalytic systems. The fact that chemical reactions which were hardly conceivable some years ago have become possible today through the development of appropriate catalytic systems proves that catalysis is in constant progress.The papers in this volume deal with studies of unit operations in catalyst preparation, catalyst preparation via the sol-gel route, preparation of catalysts from layered structures and pillaring of clays, preparation and modification of zeolite-based catalysts, carbon supported catalysts, preparation of oxidation catalysts and novel and unusual preparation methods.

This book was released on 2006-04-11 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains proceedings of the NATO-Russia Advanced Research Workshop on Nanostructured Thin Films and Nanodispersion Strengthened Coatings (December, 2003, Moscow). During this Workshop leading researchers from twelve countries had presented and discussed most recent developments in the fields of plasma physics and surface engineering related to the preparation and applications of nanostructured thin films and nanodispersion strengthened coatings. These presentations are encompassed in 31 individual chapters. The chapters are assembled in five parts in according to the workshop sessions. Part I is a compilation of chapters on hard and tribological coatings. The recent advances in this area are significant in that it is now possible to engineer strong, hard, and tough coatings that can operate at temperatures higher than 1200 ?C and exhibit ‘smart’, adaptive characteristics. These coatings are based on an amorphous matrix, e. g. nitrides, carbides, borides, or carbon, in which there is a controlled nucleation and growth of ultra hard nanoparticles of crystalline carbides, nitrides, borides and oxides. The critical feature is the control of both the particle size, i. e. , less than 10 nm, and interpartical spacing of a few nanometers. The ‘smart’ or adaptive characteristic is engineered into the nanostructures using similar sized (less than 10 nm) particles of metallic chalcogenidese, ductile metals, or glass forming elements to provide high lubricity and chemical adaptation at the environment change, e. g. , high and low humidities and temperatures.
