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. Jämförelse av torr bearbetning och minimalsmörjningseffekter på fräsning av austenitiskt rostfritt stål

   M1-uppsats, Högskolan i Gävle/Maskinteknik

   Författare :Adam Norell; Darav Hajo; [2023]
   Nyckelord :MQL; milling; stainless steel; tool wear; MQL; fräsning; rostfritt stål; verktygsförslitning;

   Sammanfattning : Fräsning och annan intermittent skärande bearbetning ger upphov till termisk utmattning av skärverktyg. Problemet med termiska sprickor blir större vid bearbetning av värmehållfasta material som austenitiskt rostfritt stål eftersom värmeväxlingarna i skärverktyget blir mer extrema. LÄS MER

4. 3. Temperature effect on insert tool life in dry machining

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :William Hagberg; [2021]
   Nyckelord :Milling tool; Temperature; Wear; Simulation; Cooling; Heat sink; Insert;

   Sammanfattning : This thesis work researched the temperature effects the insert tool life. This was examined through physical laboratory testing with designed milling tools and temperature simulations in ANSYS. The designed milling tools altered the temperature in the insert through external parameters like design and material. LÄS MER

5. 4. Built-up edge formation in stainless steel milling

   Master-uppsats, KTH/Materialvetenskap

   Författare :Axel Andersson; [2017]
   Nyckelord :Built-up edge; milling; stainless steel; tool wear;

   Sammanfattning : Milling tests were performed in stainless steel to investigate the formation of built-up edge (BUE). Three variants of tests were conducted which were divided as high-, medium, and low temperature milling tests. These tests were run in the austenitic stainless steel SS2343. LÄS MER
