16. Friction and wear in rolling and sliding contacts
Abstract : Mechanical products are always expected to perform better, last longer, be more environmentally friendly and preferably cost less. Rolling and sliding contacts are found in many mechanical products, and friction and wear in the contacts have a direct impact on the products’ ability to meet these demands. READ MORE

17. On the Nature of Cemented Carbide Wear in Rock Drilling
Abstract : WC/Co cemented carbide is a composite material for highly demanding wear applications. The unique combination of hardness (from the WC-phase) and toughness (from the binder Co) gives a material especially suitable for rock drilling. READ MORE

18. Investigation on the Influence of Nodularity in Machining of Compacted Graphite Iron (CGI)
Abstract : Stringency of environmental legislation on emission rates and increasing vehicle performance requirements are pushing the automotive and heavy truck industries to find new solutions for their diesel engines. Two potential opportunities to address these challenges involve increased combustion pressure to obtain more efficient combustion or reducing the weight of the engine. READ MORE

19. Lubrication mechanisms and properties of non-halogenated orthoborate ionic liquids
Abstract : One way to reduce energy consumption and waste - a necessity to achieve the UN-mandated limitation of average global temperature in-creases - is to select suitable lubricants so that energy-losses through friction and wear are minimised. In this context, non-halogenated ionicliquids (ILs) are promising candidates to achieve this aim due to their intrinsic ionic properties, low vapour pressure and high thermal stability. READ MORE

20. Lubrication mechanism of hydrocarbon-mimicking ionic liquids
Abstract : Lubrication is critical in order to achieve high efficiency and reliability of machine elements such as gears, bearings, and other moving mechanical assemblies (MMA). In space applications, tribological properties of lubricants are quickly growing more important. READ MORE
