1. Studie av syretillgångens inverkan på nötning av hårdmetall vid bearbetning av kopparlegeringar
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : During the production of metal zippers, cemented carbide (CC) tools are used to cut preformed brass wire into small elements. Even though the cemented carbide is much harder than the copper alloy, it gets worn and eventually the tool must be replaced. LÄS MER
2. Formation of Soft Particles in Drop-in Fuels
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : As the mission to the decrease global warming and phase out highly pollutingenvironmental practices globally, regulations including Euro 6 and policies generated by theUnited Nations Framework Convention on Climate Change (UNFCCC) are pushing companiesto be more innovative when it comes to their energy sources. These regulations involve manyfactors related to the cleanliness of the fuel and produced emissions, for example, propertiesof the fuels such as sulfur content, ash content, water content, and resulting emission valuesof Carbon dioxide (CO2) and Nitrogen Oxides (NOx).

3. Self Lubricating Components
Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaperSammanfattning : The tribological and mechanical properties are of great importance for a material’s lifetime, since it is highly dependent on these two factors. The purpose of this report was to examine suitable solid lubricants for Erasteel, a company that manufactures hot isostatic pressed high speed steels, that will enhance the tribological properties of their steels without worsening the mechanical properties.

5. Corrosion and protections of Somaloy® components
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Corrosion protection is very significant for metals in modern society from the view of industrial development. This thesis work project involves a research study that is aimed to investigate the effect of corrosion on the mechanical strength and magnetic properties of four no treated or treated Somaloy® component samples (Somaloy®700 1P, Somaloy®700 3P, Somaloy®700HR 5P and Somaloy®110i 5P) provided by Höganäs AB and laminated steel sheets by salt spray test.
