Tribometry of Materials for Bioengineering Applications
Journal Title: Tribology in Industry - Year 2010, Vol 32, Issue 1
Abstract
Development of materials for biomedical implants (metals, polymers, ceramics and composites) is directly determined by characteristics and nature of the tissue, organs and systems that are being replaced or supplemented. Modern material investigations at micro- and nano- level enable introspection into new aspects of material behaviour and offer possibilities to significantly improve systems in use, from different aspects, such as improvement of manufacturing technologies or surface technologies modifications. Biomaterial investigations from a tribology point of view offer contribution to testing realised in this area, especially with use of novel devices for research in area of nanotribology.

Friction Coefficient of Different Material Pairs Under Different Normal Loads and Sliding Velocities
In the present study, friction coefficients of different material pairs are investigated and compared. Using a pin on disc apparatus, friction coefficients of copper-copper, copper-brass, brass-brass, brass-copper pairs...
Tribological Properties of Biodegradable Universal Tractor Transmission Oil
The annual consumption of lubricants in the world is around 40 million tons out of which less than 40 % are collected and properly processed meaning regeneration, re-refining and controlled incineration while the rest is...
Carbide Type Influence on Tribological Properties of Hard Faced Steel Layer Part II- Experimental Results
In this paper is presented a preceding procedure that should be conducted in order to successfully regenerate damaged forging dies by the hard facing process. After the tool damage types identification, as well as their...
Frictional Study of Al 6061 Red-Mud Composite under the Influence of Different Process Parameters
Metal matrix composite having aluminium 6061 as matrix incorporating red mud reinforcement has been casted by employing stir casting. Scanning electron microscopy images has been taken to observe the uniformity of the re...
Steady State Thermo-Hydrodynamic Analysis of Two-Axial groove and Multilobe Hydrodynamic Bearings
Steady state thermo-hydrodynamic analysis of two axial groove and multi lobe oil journal bearings is performed in this paper. To study the steady state thermo-hydrodynamic characteristics Reynolds equation is solved simu...
