1. Wear resistant low friction coatings for engine components
Abstract : Engine development today is driven by cost, performance and government regulations. Customers want cars and trucks to consume less fuel, last longer, pollute less and be safer. Several of the requirements have tribological associations. For example, product longevity can be improved by lowering friction and using more wear-resistant components. READ MORE

2. Wear resistant low friction coatings for machine elements
Abstract : By the introduction of machine elements made of light metals, e.g. Al or Mg alloys, which are coated with a material providing high wear resistance and low friction coefficient, both economical and environmental benefits can be gained. A high resistance against wear results in increased lifetime and lower costs for spare parts and maintenance. 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. Development and tribological characterisation of magnetron sputtered TiB2 and Cr/CrN coatings
Abstract : The aim of this thesis was to develop wear resistant physical vapour deposited coatings of TiB2 as well as multilayers of Cr/CrN. The correlation between deposition parameters and fundamental coating properties such as microstructure, composition, residual stress and hardness has been investigated. READ MORE

5. Microstructural aspects on wear of cemented carbides
Abstract : Cemented carbides are known to be very wear resistant and are therefore often usedin applications involving surface damage and wear. The work presented hereinvestigates the coupling between the microstructure and some fundamental wearand deformation mechanisms typical for cemented carbides. READ MORE
