Against the backdrop of increasing energy demands, the threat of climate change and dwindling fuel reserves, finding reliable, diverse, sustainable/renewable, affordable energy resources has become a priority for many countries. Marine energy conversion systems are at the forefront of providing such a resource. Most marine renewable energy conversion systems require tribological components to c...

Current research on room-temperature ionic liquids as lubricants is described. Ionic liquids possess excellent properties such as non-volatility, non-flammability, and thermo-oxidative stability. The potential use of ionic liquids as lubricants was first proposed in 2001 and approximately 70 articles pertaining to fundamental research on ionic liquids have been published through May 2009. A lar...

Adhesive wear occurs by the transfer of material from one surface to another when two surfaces articulate against each other under load. The transferred material could break off and act as third-body particles resulting in abrasive wear. Abrasive wear occurs when material is removed from a surface by hard asperities on the counterface and hard particles (third body) trapped between the two cont...

The tribological understanding of friction and wear mechanisms and the generation of reliable friction and wear data are of increasing importance for the determination of reliability of machinery and availability of plants and transportation systems. To be of real value in reliability engineering, the tribological data should be expressed in terms of endurance life and probability of failure. T...

Abstract Tribology research mainly focuses on the friction, wear, and lubrication between interacting surfaces. With continuous increase in industrialization of human society, tribology objects have become increasingly extensive. methods also gone through stages empirical science based phenomena, theoretical models, computational simulations. has a strong engineering background. Owing to intens...

In high speed rotating machines such as turbines and generators, vibrations of a rotating shaft often hinder the smooth operation of the machine or even cause failure. Oil whip is one of such vibrations due to oil film action of journal bearing. Its mechanism and preventive method is explained and proposed in this paper. Further theoretical and experimental analyses are made for considering hea...
