   Abstract : This thesis work was conducted at Luleå University of Technology in collaboration with Sandvik Rock Tools. The aim of the work was to determine the influence of carbon content on the wear performance in carburized steel in the dry contact interface of threaded connections between drill rods. READ MORE

3. 2. The Influence of Hardness and Retained Austenite on the Fatigue Limit after Shot Peening

   University essay from Uppsala universitet/Institutionen för kemi - Ångström

   Author : Erik Björklund; [2014]
   Keywords : shot peening;

   Abstract : This thesis was performed at Scania CV AB and aimed to optimize the effect of shot peening in order to increase the bending fatigue limit of planetary gears. In this project three parameters affecting the performance of the shot peening were examined in more detail, specifically the hardness of the shot peening media, the hardness of the material and the amount retained austenite.
