Book Adhesion of Polymers to Tungsten as Studied by Field Ion Microscopy

Download or read book Adhesion of Polymers to Tungsten as Studied by Field Ion Microscopy written by William A. Brainard and published by . This book was released on 1971 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical contacts with polytetrafluoroethylene (PTFE) and polyimide polymer (PI) contacting tungsten field ion microscope emitter tips were conducted in vacuum. The metal polymer interface was examined on an atomic scale by helium field ion microscopy. Mechanical transfer was observed upon simple touch contact of the polymer materials to tungsten. The transferred polymers were stable even at the high field necessary for helium ionization, thus implying a strong chemical bonding to the metal surface. The mechanical contact stresses orient the transferred material on the tungsten surface in a radial manner from the center of contact. With sufficient load the PTFE and PI cause deformation of the tungsten. On the tungsten (110) plane, individual molecular clusters can be resolved.

Book Preliminary Studies by Field Ion Microscopy of Adhesion of Platinum and Gold to Tungsten and Iridium

Download or read book Preliminary Studies by Field Ion Microscopy of Adhesion of Platinum and Gold to Tungsten and Iridium written by William A. Brainard and published by . This book was released on 1971 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adhesion experiments with platinum and gold contacting tungsten and iridium field-ionmicroscope emitter tips were conducted in vacuum. Platinum contacting tungsten at 300 K showed an ordered surface believed to represent mechanical transfer of the platinum onto the tungsten in an ordered manner. Gold contacting tungsten at 78 K showed essentially a random transfer with some clustering of gold atoms. God transferred onto iridium by contacting at 78 K presented an ordered appearance due to decoration of ledge sites by the gold atoms. Iridium contacted by platinum showed a highly ordered surface believed to be epitaxial transfer of platinum on the surface. Contacting iridium with platinum without vibration isolation caused large globs of platinum to transfer onto iridium in an ordered manner.

Book Advances in Polymer Friction and Wear

Download or read book Advances in Polymer Friction and Wear written by Lieng-Huang Lee and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers and polymer composites have been increasinqly used in place of metals for various industries; namely, aerospace, automotive, bio-medical, computer, electrophotography, fiber, and rubber tire. Thus, an understanding of the interactions between polymers and between a polymer and a rigid counterface can enhance the applications of polymers under various environments. In meet ing this need, polymer tribology has evolved to deal with friction, lubrication and wear of polymeric materials and to answer some of the problems related to polymer-polymer interactions or oolymer rigid body interactions. The purpose of this first International Symposium was to introduce advances in studies of polymer friction and wear, especially in Britain and the U.S.S.R. Most earlier studies of the Fifties were stimulated by the growth of rubber tire industries. Continuous research through the Sixties has broadened the base to include other polymers such as nylon, polyolefins, and poly tetra fluoroethylene, or PTFE. However, much of this work was published in engineering or physics journals and rarely in chemistry journals; presumably, the latter have always considered the work to be too applied or too irrelevant. Not until recent years have chemists started to discover words such as tribo-chemistry or mechano chemistry and gradually become aware of an indispensable role in this field of polymer tribology. Thus, we were hoping to bring the technology up to date during this SympOSium, especially to the majority of participants, polymer chemists by training.

  • Author : Douglas Scott
  • Publisher : Elsevier
  • Release : 2013-10-22
  • ISBN : 1483218228
  • Pages : 517 pages

Download or read book Wear written by Douglas Scott and published by Elsevier. This book was released on 2013-10-22 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatise on Materials Science and Technology, Volume 13: Wear provides a state of the art review of wear to form a basis for all future work on the subject and to be a standard work for all in the field. The book discusses the theories of wear and their significance for engineering practice; the wear of polymers; and the wear of carbons and graphites. The text also describes scuffing with regard to its physical manifestations, its importance in practice, theoretical interpretations advanced to describe and explain its occurrence. Abrasive wear; fretting; erosion caused by impact of solid particles; rolling contact fatigue; wear resistance of metals; and wear of metal-cutting tools are also looked into. Research workers, academic personnel, and students, as well as to tribologists, designers, practicing engineers, material scientists, physicists, chemists, and petroleum technologists will find the book invaluable.
