1. On Adhesion and Galling in Metal Forming
Sammanfattning : Metal forming is widely used in the industry to produce cans, tubes, car chassis, rods, wires etc. Forming certain materials such as stainless steel, aluminium and titanium, is often difficult, and problems associated with transfer of work material to the tool material are frequent.

2. 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
3. Disperson and Flocculation in a Dry Mat-Forming Process
Sammanfattning : The absorption cores in disposable nappies, incontinence pads and female hygiene products are manufactured by a dry mat-forming process. Cellulose fibers and super-absorbing particles are suspended in air and blown onto a forming wheel on which the cores are formed. LÄS MER
4. Numerical modeling of air-fiber flows
Sammanfattning : The dynamics of fiber suspensions are of great importance in applications such as the dry-forming process of pulp mats for use in hygiene products. In this forming process, fibers are transported in flowing air. The fibers interact with the fluid, and may interact with each other and interlock in flocs. LÄS MER
5. Thermal non-coking coal preparation by triboelectric dry process
Sammanfattning : Coal is the single largest fossil fuel used world-wide and accounts for more than 60% of the total commercial energy consumed. Between 60 to 80% of this coal is used for electric power generation and most of which through a system of pulverised coal combustion. LÄS MER
