1. 1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Ahsan Ali; [2023]
   Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

3. 2. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Muhammad Hashir Zaheer; [2023]
   Nyckelord :High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

   Sammanfattning : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. LÄS MER

4. 3. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Pranay Kumar Parsi; [2023]
   Nyckelord :Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

   Sammanfattning : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. LÄS MER

5. 4. Microstructure characteristics and tribological behaviour of plasma sprayed ceramic coatings

   Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

   Författare :Luigi Fadini; [2023]
   Nyckelord :Thermal spray; APS; SPS; tribology; wear resistant ceramic coatings;

   Sammanfattning : Surface engineering is increasingly becoming inevitable for meeting the high-performance requirements constantly expected from modern engineering components. Higher demands for combined functionalities, which a base material alone cannot provide, motivate intensive academic studies on various types of coatings, with the ultimate objective of their practical utilisation in industries.
