Selected papers from those presented at the 3rd InternationalTribology Symposium of IFToMM

The International Federation for the Promotion of Mechanism and Machine Science (IFToMM) isan organisation aimed at promoting research and development in the field of machines andmechanisms by theoretical and experimental methods, along with their practical application.IFToMM has several technical committees in different fields, and one is dedicated to Tribology.The technical committee for tribology requests prominent research groups in tribology to hostand organise an international symposium on tribology. The 1st International Conference onTribology of IFToMM was held in Bejing, China, in 2008, and the 2nd symposium was organisedin Rio de Janeiro, Brazil, in 2010. The 3rd International Tribology Symposium of IFToMM wasorganised by the Division of Machine Elements of Luleå University of Technology in Swedenfrom March 19–21, 2013.The symposium was held in the Luleå University of Technology campus during three fantastic win-

ter days, providing a perfect forum for the tribologists for presenting their latest research and exchangeof ideas. The participants were also given the opportunity to experience the snowy landscape during amemorable outdoor dinner.The symposium attracted 146 participants from 26 countries. In all, 92 papers spread over 32

sessions (including six plenary sessions) were presented. These papers covered both the fundamen-tal and applied aspects of wide ranging topics such as friction, wear, lubrication, lubricants, tribol-ogy in hostile environment, tribomaterials, solid lubricants, surface engineering, tribotesting,tribological design and optimisation of machine components, modelling in tribology, biotribology,micro/nanotribology, tribotronics, tribology in power generating systems, metal working tribologyand tribology in rail and road transport. Two additional events were also organised in conjunctionwith the conference, a young researcher forum and the second international high temperaturetribology workshop.This special issue of Lubrication Science contains papers1–8 from those presented at the 3rd

International Tribology Symposium of IFToMM (ITS 2013) that were recommended by the organisingcommittee of ITS 2013.Zhmud et al.1 introduced the triboconditioning process, which is a mechanochemical surface

finishing technique developed for improving the tribological properties of mechanical componentsmade of steel or cast iron. The process combines elements of extreme pressure mechanical burnishingof the component surface with a tribochemical deposition of a low-friction anti-wear film of tungstendisulphide (WS2).

In the paper of Kaneta et al.,2 the effects of microgrooves in elliptical EHL contacts is studied bymeans of numerical analysis. The results show that the formation of microgrooves induced by localhigh pressures may influence the surface failure of machine elements.Lijesh and Hirani3 studied the stiffness and damping characteristics of a special type of rubber-

mounted hybrid bearing. For example, by softening the rubber through immersing it in an aromaticliquid, the effect of rubber Young’s modulus on the damping was studied.Courbon et al.4 focused their study on the influence of cryogenic lubrication on friction within the

context of machining TiAl6V4 and Inconel 718 alloys with carbide cutting tools. For this purpose,they used a specially designed open tribometer in order to characterise macroscopic friction coefficient,heat transfer and adhesion in the contact for a large range of sliding velocities.In the paper5 by Tuszynski et al., they performed model and component scuffing test with gear oils

formulated with biodegradable and non-toxic base oils. They draw the conclusion that rapeseed-basedgear oils can be used only for the lubrication of gears working under moderate load conditionsRajput and Sharma6 investigated the influence of micropolar lubrication on the stability of a

constant flow valve compensated multi-recess conical hybrid journal bearing system. They performednumerical simulations of the micropolar lubricated bearing system by means of a finite elementdiscretisation of a Reynolds equation modified according to Eringen theory.Lichun et al.7 studied the effect of surface texturing on friction, and wear properties of a line contact

between cylindrical and plane surfaces in sliding were investigated experimentally in mixedlubrication conditions. In their tests, lower dimple area density and larger dimple size showed a betterlubrication performance.Minami et al.8 investigated new tribosystems composed of green chemicals. For example, they

assessed the compatibility of a Zn-free lubricant with hydrogen-free amorphous DLC by means ofan SRV test machine and a friction coefficient of 0.02 with steel as counter surface.The organising committee would like to thank all the authors and delegates who made ITS 2013 a

very successful and much memorable event. Finally, the guest editors of this special issue ofLubrication Science would also like to sincerely thank all the reviewers for devoting their time andproviding their valuable inputs during the reviewing process of these papers.
