Download or read book The Influence of Surface Treatments on Micropitting and Scuffing written by and published by . This book was released on 2001 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the final report of the contract issued on 1 May 2001; this contract was a follow-on of contracts N68171-98-M-5294 and N68171-99-M-6457. Hence this report is based on an update of actions described in previous interim reports either covered by contracts N68171-98-M-5294, N68171-99-M-6457 or by the current contract. The focus of the current contract was on the scuffing performance of an ultra hard thin coating optimized for gearing applications. The original engineering background to this work was the need to understand the behavior and failure of gear tooth contacts used in demanding aerospace applications such as aircraft engine and helicopter gearboxes. Scuffing tests, designed to measure the performance of a particular combination of lubricant and gear steel, are usually impractical on lull-scale machinery, while tests using smaller gears are expensive. Furthermore, it is difficult to measure quantities of interest for research purposes, such as friction and bulk temperature. Fundamental research investigations of scuffing under controlled conditions are therefore more conveniently carried out through the use of disc machines.
Download or read book Tribology and Surface Engineering written by Aleksander Lisiecki and published by MDPI. This book was released on 2020-01-15 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers very important issues, not only scientific in nature but, ultimately, for industry and the economy. Wear and deterioration of surface properties during operation is a natural and unavoidable phenomenon. However, minimizing the degree of wear is of great importance for the entire economy, as illustrated by the example of the US economy, for which the loss of natural resources as a direct cause of friction and wear exceeds 6% of the Gross National Product. This book showcases the valuable knowledge revealed from both theoretical and practical research results in the field of advanced technologies of coatings and surface modification, as well as wear and tribological characteristics of advanced materials and surface layers. Therefore, it is hoped that this book will be a valuable resource and helpful tool for scientists, engineers, and students in the field of surface engineering, materials science, and manufacturing engineering.

Download or read book Introduction to Surface Engineering written by P. A. Dearnley and published by Cambridge University Press. This book was released on 2017-01-16 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: This highly illustrated reference work covers the three principal types of surface technologies that best protect engineering devices and products: diffusion technologies, deposition technologies, and other less commonly acknowledged surface engineering (SE) techniques. Various applications are noted throughout the text and additionally whole chapters are devoted to specific SE applications across the automotive, gas turbine engine (GTE), metal machining, and biomedical implant sectors. Along with the benefits of SE, this volume also critically examines SE's limitations. Materials degradation pathways - those which can and those which cannot be mitigated by SE - are rigorously explained. Written from a scientific, materials engineering perspective, this concise text is supported by high-quality images and photo-micrographs which show how surfaces can be engineered to overcome the limits of conventionally produced materials, even in complex or hostile operating environments. This book is a useful resource for undergraduate and postgraduate students as well as professional engineers.
Download or read book An Investigation Into the Influence of Surface Pre Treatment by Particle Impact on the Strength of Adhesive Joints Between Like Steel Surfaces written by R. W. Atkins and published by . This book was released on 1973 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study is made of the effect of particle impact surface pre-treatment (grit blasting) ON THE BONDING OF STEEL SURFACES USING A STRUCTURAL ADHESIVE. Mile steel and stainless steel cylinders are prepared for bonding by eighteen different methods of grit blasting and three methods of chemical pre-treatment. The cylinders are then bonded two by two co-axially using an epoxy film adhesive cured at 100 -180 C. The influence of different abrasive powders, nozzle pressures and angles of incidence between the jet and the adherend surface, on the joint strengths produced, is measured by stressing the joints in shear and in tension.

Emphasis is on the properties of carburized steels, the material of choice for high-performance power transmission gearing.
Download or read book Chemistry and Technology of Lubricants written by Roy M. Mortier and published by Springer Science & Business Media. This book was released on 2011-04-14 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Chemistry and Technology of Lubricants" describes the chemistry and technology of base oils, additives and applications of liquid lubricants. This Third Edition reflects how the chemistry and technology of lubricants has developed since the First Edition was published in 1992. The acceleration of performance development in the past 35 years has been as significant as in the previous century: Refinery processes have become more precise in defining the physical and chemical properties of higher quality mineral base oils. New and existing additives have improved performance through enhanced understanding of their action. Specification and testing of lubricants has become more focused and rigorous. "Chemistry and Technology of Lubricants" is directed principally at those working in the lubricants industry as well as individuals working within academia seeking a chemist's viewpoint of lubrication. It is also of value to engineers and technologists requiring a more fundamental understanding of the subject.
