1. On wear of wood-cutting tools : Tool materials, wear mechanisms and modelling
Abstract : Bandsaw blades are commonly used in the sawmill industry for timber cutting. The saw teeth are gradually worn during cutting and will finally cause unacceptable surface roughness and dimensional deviations on the sawn wood product. Maintenance by re-sharpening of the saw teeth is therefore necessary after a certain time of sawing. READ MORE

2. 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

3. A Ni3Al-alloy and its Composites as Potential Wear Resistant Materials for Advanced Applications
Abstract : The Ni3Al-based intermetallic alloys as engineering materials in service, they may be subjected to a wear environment of some sort. Hence, it is technologically important to understand the tribological response and to determine methodologies to improve wear resistance of these advanced materials. READ MORE

4. Wear mechanisms in sheet metal forming : Effects of tool microstructure, adhesion and temperature
Abstract : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of lubricants, in combination with the introduction of high and ultrahigh-strength sheet materials, continuously increases the demands on the forming tools. READ MORE
