The tribology of flexible magnetic recording media—the influence of wear on signal performance

The tribology of magnetic recording systems is different to conventional tribology in many important aspects and an understanding of this branch of the science is still in its infancy. This paper presents a review of one specific aspect of the tribology of flexible tape storage systems, that is wear of heads and media and the effect on signal performance. Based on the work of this author's group and others and with reference to classical tribological principles, the various mechanisms of wear have been identified in particulate media, metal evaporated media and various recording head types and have been discussed in terms of the effect of signal degradation and error or drop out production. From this review, the wear mechanisms and surface and subsurface parameters which should have the most influence on the future development of media and systems are identified.     

The application of Raman spectroscopy to the tribology of polymers

This paper reviews the use of Raman spectroscopy for investigations in polymer tribology. In particular, a number of studies dealing with the problem of surface plasticisation in engineering polymers have been reported and are reviewed in this paper. Solvent and thermally-induced plasticisation have been examined using Raman spectroscopy. The polymers poly(ether ether ketone), nylon and polycarbonate have been investigated and are discussed here.     

Molecular tribology of disk drives

A good molecular level understanding of the tribological properties of the materials at the slider-disk interface is essential to the future development of disk drive technology. This paper provides a short overview of the molecular tribology of disk drives related to the selection of lubricant materials for the slider-disk interface. Besides providing criteria for lubricant selection, this paper briefly discusses our current understanding of stiction and friction forces, lubricant degradation, lubricant mobility, spin-off, and lubricant transfer to sliders. This revised version was published online in June 2006 with corrections to the Cover Date.

Self-lubricating polymer composites and polymer transfer film lubrication for space applications

The use of self-lubricating polymers and polymer composites in space is somewhat limited at present. In general, they are only used when other methods are inadequate. There is potential, however, for these materials to make a significant impact on future space missions, if properly utilized. This paper surveys some of the different polymers and fillers used to make self-lubricating composites. It delves into the mechanisms of composite lubrication and wear, the theory behind transfer film lubricating mechanisms, and some factors which affect polymer composite wear and transfer. In addition, some of the current space tribology application areas for self-lubricating polymer composites and polymer transfer are mentioned.

Study on the tribological behaviors of polyelectrolyte multilayers containing copper hydroxide nanoparticles

In this paper, we reported the tribological behaviors of polyelectrolyte multilayers (PEMs) containing copper hydroxide nanoparticles, polymer films were prepared by the sequential adsorption Poly(diallyldimethylammonium chloride) (PDDA) and poly(sodium 4-styrenesulfonate) (PSS) alternately on substrate. The nucleation of copper hydroxide nanoparticles was achieved using a cyclical absorption-hydrolysis process in which copper ions were absorbed into the polymer matrix (which bind to the sulfonate groups) and then hydrolysis in an alkali solution. The structure and the morphology of before and after the in-situ synthesis copper hydroxide nanoparticles in the PEMs matrix have been explored. The coefficient of friction as a function of sliding velocity and normal load also has been studied. The composites exhibited increased wear resistance compared with the pristine polymer films. This may partly be attributed to the enhanced load-carrying capacity of the inorganic nanoparticles in the PEMs. Dr. Pingyu Zhang, Professor of Laboratory for Special Functional Materials, Henan University.

He worked on tribological study in State Key Laboratory of Solid Lubrication, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences 1983 to 2003.

Experiment and computer simulation of particulate suspensions under shear flow

In this paper is described the role of molecular simulation as a useful quasi-‘experimental’ tool to help in understanding the interplay between molecular structure under shear flow and the manifested tribology/rheology. The development of non-equilibrium molecular simulation techniques are discussed, from the molecular dynamics approach through to the modelling of dispersions by brownian dynamics. Recent advances and extensions of the technique to weakly flocculated systems, such as electro-rheological fluids, are described.

New Asian Case Method for tribology: a structured approach for increased problem solving competence in tribology teaching and research

Abstract

The gap between academic science/engineering and industry concerning problem solving competencies is addressed in this paper by proposing the New Asian Case Method, an approach inspired by, but substantially different from, the trademark of professional education of the Harvard Business School. The paper puts forward the idea that knowledge in tribology shall be arranged in cases with practical examples that allow students and researchers to learn tribology on real world problems, and obtain a toolbox they subsequently use in their work as tribologists in academia or industry. Micro- and nanotribology are accentuated as high potential role model fields for successful interdisciplinary, inherently application oriented approaches. The New Asian Case Method increases quality approaches in tribology, by structuring the ways of thinking and addressing problems. Establishing the New Asian Case Method in tribology shall set the basis for an international standard in the field.     

The temperature and pressure dependence of viscosity and volume for two reference liquids

The new quantitative elastohydrodynamics has resulted in rapid advances in understanding concentrated contact lubrication behaviour by employing real transport properties. A key component of this revolution has been the use of reference liquids. In this paper, two liquids, a triester and a perfluoropolyether, which are under consideration as possible viscosity standards are characterised to 1 GPa for conditions relevant to tribology. Two correlations are provided for interpolation and data smoothing, and an explanation for difficulties encountered with free volume theory is offered. The perfluoropolyether is only appropriate as a reference liquid when an identical lot is available. Copyright © 2015 John Wiley & Sons, Ltd.

Tribology of the belt-driven data tape cartridge

The belt-driven data tape cartridge uses an elastic drive-belt to control magnetic tape tension by driving both tape supply and take-up reels. This design enables the use of a simple, compact and inexpensive cartridge drive mechanism. However, there were many tribological issues that had to be solved before this product reached its current widespread acceptance in the data storage market. This paper will address the associated friction and wear control issues. The main focus will be on polymer tribology and how attention to the micro-tribological details of each interface has been linked with improved data storage reliability and performance.

A Final year undergraduate lecture course on tribology

An outline syllabus is presented for an integrated lecture course on tribology appropriate for the final year of an undergraduate honours degree scheme. It is suggested that in a course of about 24 lectures the subject can be treated in adequate breadth and depth to provide an understanding of tribology useful to the professional engineer, and to form a foundation for further study and reading. The educational merit of such a course is believed to be much greater than just the transmission of tribological information to the student, in that it illustrates important characteristics of many technological disciplines. It demonstrates amongst other things that not all theory is rigid and well proven, that sometimes gross assumptions must be made to permit any mathematical analysis to be carried out, that many unpredictable and varied factors affect component life, and that the understanding of a subject is continually being improved by research.
