11. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. READ MORE

12. Dual Polarized Geodesic Lens
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Gradient-index (GRIN) lens antennas, such as the Luneburg lens, posses attractive electromagnetic properties. The smooth change in refractive index ensures no internal reflections and the focusing of the electromagnetic waves results in a directive antenna. The main challenge of the design of a GRIN lens is acquiring the required refractive index. READ MORE

15. Characterization of thin laminate interface by using Double Cantilever Beam and End Notched Flexure tests
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : This thesis is intended to identify the mode I and mode II fracture toughness to characterize the thin laminate interface by using the Double Cantilever Beam test (DCB) and End Notched Flexure test (ENF). This study’s thin laminate was Polyethylene Terephthalate and Low-Density Polyethylene (PET-LDPE), which is mostly used by packaging industries in the manufacturing of packages to store liquid food.
