This book is a long-awaited contribution to the field of tribology a valuable addition to our tribological references and a particularly good reference source for the understanding of the friction and wear properties of polymers in various states and under a variety of mechanical ation EngineeringAuthor: G. M. Bartenev. Thus, friction of polymers as a function of load varies in the manner, which was described by Kragelskii. That is, the friction coefficient passes a minimum, which corresponds to transition from elastic contact (left descending branch of the curve) to Cited by:   The book is organized into three parts. The chapters in Part I cover the basic laws of friction and wear in polymer-based materials. Topics covered include frictional interaction during metal-polymer contact and the influence of operating conditions on wear in Edition: 1. Friction is defined as the resistance to sliding motion and is measured in terms of the coefficient of friction, which is the ratio of the force necessary to cause sliding between two bodies in contact and the normal force pressing these bodies together.

Specifically dedicated to polymer and biopolymer systems, Polymer Adhesion, Friction, and Lubrication guides readers to the scratch, wear, and lubrication properties of polymers and the engineering applications, from biomedical research to automotive engineering. Author Hongbo Zeng details different experimental and theoretical methods used to probe static and dynamic Cited by: Friction plots of polymers sliding on smooth metal surfaces are generally characterized by two regions of distinct dependency on the normal load, with low sensitivity at low stress levels followed by a sharp change in the rate of decrease of friction with increasing pressure at levels above the plastic flow limit of the polymer. A simplified model is proposed to describe this behavior which Cited by: It is my ambition in writing this book to bring tribology to the study of control of machines with friction. Tribology, from the greek for study of rubbing, is the discipline that concerns itself with friction, wear and lubrication. Friction and the Fluorocarbons Most polymers have coefficients of friction in the range to but the fluorocarbons generally have lower coefficients of friction than this range. PTFE has the lowest recorded m value for any material with a dynamic coefficient of friction of between and and a static coefficient ofFile Size: KB.

In the past few decades, organic thermoelectric materials/devices, which can exhibit remarkable potential in green energy conversion, have drawn great attention and interest due to their easy processing, light weight, intrinsically low thermal conductivity, and mechanical flexibility. Compared to traditional batteries, thermoelectric materials have high prospects as alternative Cited by: 4. Polymers experience friction as they flow along a stationary object, whether it is the barrel or part of a mold. Elongational flow occurs when a fluid is being stretched in the direction of flow. This action takes place through the acceleration of the fluid elements along a streamline. The objective of this work is to analyse the influence of interfacial properties on the sliding friction of polymers. In order to change the nature of interface, two types of smooth and rigid. Minimization of Wear of Polymers by Plasma Treatment • Crystalline polymers: HDPE, POM • Amorphous polymers: PMMA, PC • CASING (Cross-linking by activated species of inert gases) • Helium plasma (1 torr, MHz, Watts, Room temp.) for and seconds • Pin-on-disk, Normal load = N, speed = cm/s.
