11. Surface integrity and corrosion behavior of stainless steels after grinding operations
Sammanfattning : Stainless steels are widely used in applications where both the mechanical properties of steels and high corrosion resistance are required. There is continuous research to enable stainless steel components to be produced in a more economical way and be used in more harsh environments. LÄS MER
12. Surface Engineering in Sheet Metal Forming
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
13. Tribology in Metal Working
Sammanfattning : This thesis focuses on the tribological performance of tool surfaces in two steel working operations, namely wire drawing and hot rolling. In all forming operations dimensions and surface finish of the products are of utmost importance. LÄS MER
14. FE-Simulation of Metal Cutting Processes
Sammanfattning : Machining a new component or a new material requires the selection of the cutting conditions, the tool material and the tool geometry. The selections should be also optimized for the existing components and materials to improve the quality of the produced components and reduce the cost of production. LÄS MER
15. Galling of high strength steels and stainless steels in sheet metal forming as evaluated using pin-on-disc testing
Sammanfattning : The thesis focuses on the problem galling in sheet metal forming operations. Galling occurs when sheet metal transfers from the sheet surface onto the tool surface and causes surface damages to following sheets in the forming operation. When this happens the tool must be replaced causing production stops and additional expenses. LÄS MER
