1. Workpiece steels protecting cutting tools from wear : A study of the effects of alloying elements on material transfer and coating damage mechanisms
Sammanfattning : The vision of this thesis is to improve the machinability of workpiece steels. Workpiece material frequently transfers to the cutting tools during machining, and the transfer layers then forming on the tools may give both good and bad effects on machining performance and tool life.

Sammanfattning : The introduction suggests a model for defining and categorising different types of graffiti, and the term TTP (Tags/Throw-ups/Pieces) is presented. Chapter I relates the body of research up to the present day and proposes a comprehensive interpretation, based partly on English and German subculture- and socialisation theories. LÄS MER

4. Particle emissions from car brakes : The influence of contact conditions on the pad-to-rotor interface
Sammanfattning : Due to their adverse health effects emissions have been regulated for over three decades. Brake wear particulate matter is the most important non-exhaust source, however current knowledge is mainly limited to observational studies. LÄS MER
Sammanfattning : Recent developments in thin film synthesis of diamond have facilitated a host of new technical applications. These are motivated by the many attractive properties of diamond, for example high hardness, chemical inertness, transparency and heat conductivity. Unfortunately, these properties also make it difficult to fashion complex geometries. LÄS MER
