4. 2. Surface Engineering in Sheet Metal Forming

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Per Carlsson; Uppsala universitet.; Högskolan Dalarna.; [2005]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science; Materials science; Friction; wear; metal coated steel sheet; dry lubricants; galling; PVD coatings; Materialvetenskap;

   Abstract : 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. READ MORE

5. 3. Development and tribological characterisation of magnetron sputtered TiB2 and Cr/CrN coatings

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Mattias Berger; Uppsala universitet.; [2001]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; TiB2; Tribology; Magnetron Sputtering; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science;

   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

6. 4. Tribological nature of squealing disc brakes

   University dissertation from Uppsala : Acta Universitatis Upsaliensis
