Towards the end of the year, we tribologists had two great reasons to celebrate. On 31<sup>st</sup> August 2017, The Finnish Society for Tribology reached the cornerstone of 40 years. The 40<sup>th</sup> anniversary was commemorated through an international seminar, after which the festivities continued with celebratory dinner and speeches. The day offered many interesting presentations, discussions and possibilities for networking. The readers of Finnish Journal of Tribology are provided with an overview of the 40<sup>th</sup> Anniversary seminar. Just before the Christmas, professor Kenneth Holmberg from VTT Technical Research Centre of Finland Ltd received the highest international award in the tribology field, The Tribology Gold Medal Award. Finnish Journal of Tribology wants to congratulate Kenneth for this great achievement! This end-of-year issue therefore reviews the award declaration for the readers.<br><br> I hope the New Year will be as prosperous for the tribologists as the ending one.<br><br><em>Elina Huttunen-Saarivirta<br></em>Editor-in-Chief of Finnish Journal of Tribology</p> Elina Huttunen-Saarivirta Copyright (c) 2017 Elina Huttunen-Saarivirta Sun, 31 Dec 2017 00:00:00 +0200 Investigation of physicochemical and tribological properties of TiO2 nano-lubricant oil of different concentrations <p>Nano-lubricants provide enhanced tribological properties in several applications like machines and engines. The presence of nanoparticles in the lubricating oil effects its wear, friction, thermal, chemical and physical properties in many ways. This article reports effect of TiO2 nanoparticles suspended in servo system lubricating oil prepared by sonication process without adding any surfactant. Four different volume concentrations (0.2%, 0.4%, 0.6% and 0.8%) of TiO2 nanoparticles in the base lubricating oil are used for analysis. Calorific value, flash point, viscosity are the physicochemical properties of the TiO2 nano-lubricant investigated at different Volume Concentrations (VC). Wear scar diameter and coefficient of friction are the tribological properties analyzed for the prepared nano-lubricant at different VCs. Calorific value and flash point of the nano-lubricant was found to be decreasing with increasing VCs compared to base lubricant oil. Viscosity, on the other hand was almost same as the base lubricant oil for the proposed VCs. Wear scar diameter and friction coefficient was found to increase with increase in VC of TiO2 nanoparticles in the lubricant oil. It is concluded that, to obtain better results agglomeration of nanoparticles has to be avoided which can be achieved with the use of surfactant.</p> Mohan Kumar, Asif Afzal, Ramis M K Copyright (c) 2017 Mohan Kumar, Asif Afzal, Ramis M.K Sun, 31 Dec 2017 00:00:00 +0200 Focus on friction and wear - The 40th anniversary seminar of the Finnish Society for Tribology in Tampere <p>The Finnish Society for Tribology was founded 31.8.1977 to promote the research, technical development and education of tribology in Finland. The society publishes the quarterly journal Tribology and arranges conferences, seminars and special events on tribology. The society celebrated its 40 years existence by arranging an international commemorative seminar in the Finnish Labour Museum Werstas located in the former buildings of Finlayson factories in Tampere.</p> Tuomo Tiainen Copyright (c) 2017 Tuomo Tiainen Sun, 31 Dec 2017 00:00:00 +0200 Kenneth Holmberg from VTT Technical Research Centre of Finland Ltd won the highest international award in the tribology field <p>On 20 December, the Tribology Trust presented VTT's<strong> Kenneth Holmberg</strong> with the most highly prized award in the field, the Tribology Gold Medal Award, for his long-standing, major achievements in material and friction research.
