    Sammanfattning : In recent years, surface engineering techniques have been developed in order to improve the tribological performance in many industrial applications. In sheet metal forming processes, the usage of liquid lubricants can be decreased by using self lubricated tribo surfaces which will result in more environmentally friendly workshops. LÄS MER

  3. 3. High aspect ratio microsystem fabrication by ion track lithography

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
