This book was released on 2013 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fretting wear is considered as a complex wear phenomenon related to interaction between two sliding bodies under very low displacement amplitude, which limits the lifetime of elements significantly. Solid lubricant is more and more applied in tribological applications to reduce friction and protect the substrate surface from fretting wear. The performance of coating depends on many factors such as running conditions, properties of substrate, counterbody and coating, and adhesion between coating and substrate. The objectives of this thesis are to discuss the friction and wear behavior of the coating under different running conditions, and to analyze the effect of test parameters on the friction coefficient and lifetime of the coating, which can be effectively helpful for the evaluation of quality of the coating. Fretting experiments are carried out to understand the relationships between the tribological behavior of a MoS2 based varnish coating and running conditions. The coating is investigated under different contact forces, different displacement amplitudes, different contact configurations, different coating positions, different substrates and different thicknesses. The rank of effect of factors is evaluated by the analysis of variance. Regression analysis is used to predict the performance of coatings under certain running conditions. The observation of evolution of wear scar is applied to explain the rank of factor and coefficients in the prediction equations. Furthermore, the reliability analysis is used to describe and predict the survival rate of coatings under certain running conditions. Finally, a linear model for lifetime is assessed in order to take into account variable displacement amplitude.

This book was released on 1993-11-19 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides final year undergraduate students, graduate students, research scientists and engineers with an up-to-date overview of the power of using surface analytical techniques for probing complex solid surfaces and lubricants as well as for understanding their interactions in tribological systems. The first three introductory chapters illustrate the need for surface analysis in tribology and the essentials of the analytical techniques. Following these, eight chapters on applications give insight into the contribution of the major analytical techniques to tribology. These chapters are divided into three groups. The first group deals with the applications of surface analytical techniques to the study of the adhesion, friction, deformation, wear, structure and chemistry of solid surfaces at the atomic scale or in well-defined conditions. The second group focuses mainly on solid lubricants and tribological surface modifications. Lastly, the third group covers liquid lubricants in molecularly thin-film lubrication and in boundary lubrication and their interactions with surfaces.
Download or read book Nanolubricants written by Jean Michel Martin and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technology involved in lubrication by nanoparticles is a rapidly developing scientific area and one that has been watched with interest for the past ten years. Nanolubrication offers a solution to many problems associated with traditional lubricants that contain sulphur and phosphorus; and though for some time the production of nanoparticles was restricted by the technologies available, today synthesis methods have been improved to such a level that it is possible to produce large quantities relatively cheaply and efficiently. Nanolubricants develops a new concept of lubrication, based on these nanoparticles, and along with the authors’ own research it synthesises the information available on the topic of nanolubrication from existing literature and presents it in a concise form. Describes the many advantages and potential applications of nanotechnology in the tribological field. Offers a full review of the state-of-the-art as well as much original research that is yet unpublished. Includes sections on boundary lubrication by colloïdal systems, nanolubricants made of metal dichalcogenides, carbon-based nanolubricants, overbased detergent salts, nanolubricants made of metals and boron-based solid nanolubricants and lubrication additives. Authored by highly regarded experts in the field with contributions from leading international academics. Nanolubricants will appeal to postgraduate students, academics and researchers in mechanical engineering, chemical engineering and materials science. It should also be of interest to practising engineers with petroleum companies and mechanical manufacturers.

Download or read book Influence of Test Parameters on Tribological Results Synthesis from Round Robin Tests written by M. Woydt and published by . This book was released on 2001 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of cooperative interlaboratory tests (round robins) was conducted in 1997, 1998 and 1999 by the DIN 51834 Working Group on Tribological Tests in Translatory Oscillation Apparatus. The statistical analysis of these test results shows the influence of cleaning solvent, machine model and evaluation criteria on the tribological properties of the lubricants tested. Coefficients of friction and wear results are ranked according to the effects of ten different cleaning solvents, where isopropanol gave the lowest values and isoparaffin solvents the highest. The effect of machine model on coefficients of friction varied from about 0.2 % to 0.9 % of the average. Wear results were not affected. The tests also showed that the seizure criteria and methods of measuring wear required for in the test procedure do not provide a suitable measure of the tribological properties of some lubricants.
