| etching solution for steel: Metallography of Steels: Interpretation of Structure and the Effects of Processing Hubertus Colpaert, 2018-08-01 Updated and translated by André Luiz V. da Costa e Silva This book is a combination of a metallographic atlas for steels and cast irons and an introductory textbook covering the fundamentals of phase transformations and heat treatment of these materials. Every important stage of processing, from casting to cold working is clearly discussed and copiously illustrated with metallographs that show the obtained structures, both desired and those achieved when deviations occur. First published in 1951 by Professor Hubertus Colpaert from the Institute for Technological Research (IPT) of São Paulo, Brazil, this book became one of the most important Brazilian references for professionals interested in the processing, treatment, and application of steels and cast irons. In the Fourth Edition and English translation, updated and translated by Professor André Luiz V. da Costa e Silva, the concept of the of the original edition was preserved while the important developments of recent decades, both in metallographic characterization and in steel and iron products, as well as progress in the understanding of the transformations that made the extraordinary developments of these alloys possible, were added. Most metallographs are of actual industrial materials and a large number originate from industry leaders or laboratories at the forefront of steel and iron development. As steel continues to be the most widely used metallic material in the world, Metallography of Steels continues to be an essential reference for students, metallographers, and engineers interested in understanding processing-properties-structure relationships of the material. The balance between theoretical and applied information makes this book a valuable companion for even experienced steel practitioners. |
| etching solution for steel: The Complete Technology Book on Electroplating, Phosphating, Powder Coating And Metal Finishing NIIR Board, 2005-10-04 Electroplating and Metal Finishing concerns itself with the development and applications of composites and non metallic coatings. These coatings are used for decorative, protective and functional application. Some of the other common metal surface finishing technologies are phosphating, pickling, electroforming, powder coating etc. Electroplating is the process of applying a metallic coating to an article by passing an electric current through an electrolyte in contact with the article, thereby forming a surface having properties or dimensions different from those of the article. Metal finishing has now come to be known as surface engineering. Surface engineering techniques are generally used to develop a wide range of functional properties. In addition to the decorative aspects, metal finishing aids the protection of metals and alloys from corrosion and rusting. A great potential exists for development of new materials involving, for example, coatings of metals composites particle incorporated anodic coatings and even films of sapphire like materials, porous files of niobium etc. and coating of refractory metals like molybdenum and tungsten. Phosphate coatings have a wide field of application in manufacturing industry, both as an aid to mechanical production operations and in surface finishing. The major applications for phosphate treatments fall into four areas; pre treatment prior to organic coatings, protection against corrosion, anti wear coatings and phosphating as a production aid. Powder coating of aluminium, extrusions in particular, has become an important feature in the finishing of aluminium. There are several advantages of powder; powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating, powder coating production lines produce less hazardous waste than conventional liquid coatings, capital equipment and operating costs for a powder line are generally less than for conventional liquid lines. Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. Currently, the trend is towards surface treatments. Industries in developing countries like India have to be increasingly aware of the need not only for up gradation of existing technologies but also for indigenization of new technologies on a time bound basis. The content of the book includes information about technology involved in surface engineering of metals; some of them are electroplating plant, barrel planting plant, electroplating equipment, cleaning, pickling and dipping, equipment for hot alkaline cleaners, electrolytic and chemical processes for the polishing of metals, canning stainless steel electro-polishing solution, electroforming in gramophone record production, silver plating, fluoborate plating, gold plating (gilding), cadmium plating, zinc plating, chemical finishing of aluminium, powder coating of aluminium, bright nickel electro plating, copper plating, etc. This book covers an intensive study of technology of electroplating, phosphating, powder coating and metal finishing. The first hand information on these technologies is dealt in the book and can be very useful for those looking for entrepreneurship opportunity in the said industry.
