To produce electricity, stress is directly put generator based upon rating of the generator and type of slip over the natural resources like fossil fuels, water, metals by means of ring used because width of rings in the slip ring and diameter either hydraulic power generation or thermal power generation and (outer diameter) of slip ring is the deciding factor for selection in this era, we also generate by nuclear power. To achieve the need of type of carbon brush holder. For example, if the width of of power generation, the setup to produce electricity consists of rotor, stator, different types of windings such as stator winding, rotor ring of slip ring is 10.05 mm then carbon brush of width 10.05 winding, slip rings, carbon brush holder and different types of mm can only be used neither lesser nor bigger. Thus, pocket connections. Several metals and chemicals are used to electroplate size of carbon holder must be of 10.05 mm which means the carbon brush holder such as copper, brass, CuSO4, H2SO4.

Even if the galvanic electrodeposition is certainly a mature technology, new concepts, novel applications, environmental legislation and the new material requirements for next-generation devices make the scientific research in this field still very active. This review focuses mostly at the decorative and wearable applications, and aims to create a bridge between the past knowledge and the future direction that this process, i.e., electrodeposition, is taking.

This has come about largely as a result of extensive research in the field of electrodeposition, especially during the past 25 years. To encourage further research in this field, to present current re- search results and problems, and to facilitate the exchange of informa- tion, the National Bureau of Standards held the Symposium on Electrodeposition Research as the last of a series of twelve symposia conducted during the Bureau’s semicentennial in 1951. The papers presented at the Symposium are published in this volume. These papers represent a cross section of research currently being conducted in electrodeposition by industrial, university, and government labora- tories in Europe and the United States.

    2007 American WJTA Conference and Expo August 19-21, 2007 ● Houston, Texas Paper CONSIDERATIONS IN THE USE OF PULSED WATER JET TECHNIQUES FOR THE REMOVAL OF HVOF COATINGS Andrew Tieu, Wenzhuo Yan and Mohan Vijay VLN Advanced Technologies Ottawa, Ontario, Canada ABSTRACT Thermal spray coatings are becoming increasingly common in a wide variety of industrial applications. Specifically, Tungsten Carbide - High Velocity Oxygen Fuel (HVOF) coating, which is a derivation of thermal spray technology, is currently being tested on landing gear components. The authors have conducted extensive laboratory work on the removal of HVOF coatings from landing gear pins and other aircraft/aerospace components using forced-pulsed waterjet (FPWJ). These tests were conducted at pressures ≤ 104 MPa (15 kpsi) using only pure (tap) water. Several measurements were taken to assess the performance, and to ensure that the process meets the criteria specified by the aircraft/aerospace industry. Surface roughness measurements, taken by one of the aerospace companies, indicated no significant difference between the measurements taken before and after the removal process, indicating the substrate experienced minimal to no surface damage. Post stress analysis of the substrate, using x-ray diffraction technique, showed compressive stresses initially induced by peening to improve fatigue life, was not relieved by the removal method. Organized and Sponsored by the WaterJet Technology Association 1 INTRODUCTION Thermal-spray coatings are becoming increasingly common for coating in a wide variety of industrial applications.

  • Special Aspects of Electrodeposition on Zinc Die Castings
    NASF SURFACE TECHNOLOGY WHITE PAPERS 82 (8), 1-9 (May 2018) Special Aspects of Electrodeposition on Zinc Die Castings by Valeriia Reveko1,2* and Per Møller2* 1Collini GmbH, Hohenems, Austria 2Technical University of Denmark, Lyngby, Denmark ABSTRACT Metal die casting has become a popular choice for the manufacturing of different consumer goods. Among the various engineering alloys and other metals, zinc alloys have often been preferred by manufacturers due to their qualities such as castability, dimensional stability and moderate solidification temperature, which provides energy and cost savings. Electroplating is a frequent choice to give zinc die cast components a high quality protective and decorative surface finish. However, applying this kind of treatment for die cast zinc components presents hidden challenges. In order to overcome these issues, a thorough morphology and composition analysis of die cast items was conducted. Special aspects of zinc die cast as a plating substrate are described and linked to the die casting process. Keywords: electrodeposition, zinc die cast, surface finishing, electroplating defects Introduction: why do we need to improve zinc die cast parts? Currently, metal die casting has become a popular choice for the manufacturing of finished products. An increasing number of industrial producers are attracted by this highly economical and efficient process capable of providing near-net shaped components that fully satisfy the geometrical requirements. Zinc, as a basis material, offers a broad range of desirable properties, beginning with hardness, ductility, impact strength, self- lubricating characteristics,1 and exhibits excellent thermal and heat conductivity. Among the various engineering alloys and other metals, zinc alloys have often been preferred by manufacturers because of their castability, dimensional stability and moderate solidification temperatures, which provide significant energy and cost savings.
