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

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ahsan Ali; [2023]
   Keywords : 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;

   Abstract : 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. Study of Porosity in Uncoated Cemented Carbide Tools During Titanium Alloy Machining.

   University essay from Lunds universitet/Industriell Produktion

   Author : Cornelis Botermans; [2023]
   Keywords : Technology and Engineering;

   Abstract : During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. READ MORE

4. 3. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Emil Treitler; [2022]
   Keywords : Fatigue; Kaplan; Hydropower; Turbine;

   Abstract : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. READ MORE

5. 4. 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 matematik

   Author : Cecilia Nemeth; [2020]
   Keywords : high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

   Abstract : 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

6. 5. Use of compliant mechanisms in gearbox applications

   University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Author : Álvaro Manresa Pérez; Ander Gonzalez Sanchez; [2020]
   Keywords : compliant mechanisms; product development; Finite Element Analysis; additive manufacturing;

   Abstract : The purpose of this thesis is to prove that the use of compliant mechanisms in gearbox applications is viable. Compliant mechanisms are developed for their implementation in Scania’s hybrid asynchronous gearboxes. READ MORE
