Novel Oxyfluoride Biophotonic Glass-Ceramics
(2019)
Diplomityö
Diplomityö
Phosphate glasses are very interesting due to several properties, such as good thermal and mechanical stabilities, high transparency, low refractive index, low melting temperature and high gain density (Wa,03; Pr,08; Hr,13; ...
Corrosion of Cruise Vessel Outfitting Parts
(2019)
Diplomityö
Diplomityö
Corrosion causes huge costs for ship industry. Marine environment is very corrosive and the presence of marine salts accelerate corrosion and may cause local corrosion. High humidity of marine environment also has an ...

Pro gradu -tutkielma
The purpose of this thesis is to design and analyse the structure of a directional antenna. The directional antenna is part of The Autonomous and Collaborative Offshore Robotics project, an exercise developed by the Tampere ...
Thermogravimetric analysis of resized glass and carbon fibers
(2019)
Diplomityö
Diplomityö
The demand in growth for composite products over the years has as a consequence increased the volume of composite waste, requiring adequate waste management beyond incineration or landfilling practices. Current composite ...
Non-destructive testing of additively manufactured steel components
(2019)
Diplomityö
Diplomityö
Additive manufacturing (AM) is a relatively new manufacturing method, which is capable of producing complex geometries and parts on-demand from multiple different materials. Metal AM, with all its advantages, has some ...

(2019)
Diplomityö
Diplomityö
Paper and paperboard material can be used for applications of a different kind, for example in packaging materials such as food packages. For food packages one important requirement are the barrier properties, which can ...
Surface characterization of ground surfaces: effects of grinding
(2019)
Diplomityö
Diplomityö
Thesis was focused on to the effects of grinding and the surface characterization of the ground surfaces. Main focus was in Barkhausen noise (BN) and its use in surface characterization measurements done to the assigned ...
Effect of Microstructure on Brittle Fracture Initiation in a Reactor Pressure Vessel Weld Metal
(2019)
Diplomityö
Diplomityö
The weld can be the most life-limiting part in a reactor pressure vessel (RPV). During operation, the pressure vessel components are subjected to high temperature and neutron irradiation induced ageing, which cause ...
Effect of specimen geometry and friction in the high strain rate compression tests
(2019)
Diplomityö
Diplomityö
The Split Hopkinson pressure bar (SHPB) or Kolsky bar is widely used to characterize the mechanical behavior of materials at different strain rates and different temperatures. The proper characterization of mechanical ...
Productization of a new type of dielectric elastomer actuator
(2019)
Diplomityö
Diplomityö
Dielectric elastomer actuators (DEAs) occupy a niche in haptic technology, and Senseg Oy has developed a new type of DEA that is suitable also in haptic applications: a product called Elastomer Film Actuator (ELFIAC). ...
