  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. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

    Master-uppsats, Karlstads universitet

    Författare :Marcus Roseen; [2023]
    Nyckelord :;

    Sammanfattning : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. LÄS MER

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Atle Andersson Nykvist; [2023]
    Nyckelord :Tribology; friction; wear; hot wear; hot wear tester; design; construction; tribometer; tribo tester; tribo-tester; Tribologi; friktion; nötning; varmnötning; varmnötare; design; konstruktion; tribometer; tribotest;

    Sammanfattning : There are two main goals of this thesis. Firstly, to improve and develop an existing hot weartester at Karlstad University so that it may test more samples of different sizes. Secondly, totest previously impossible samples and investigate their tribological properties and measurethe coefficient of friction with high reproducibility. LÄS MER

  5. 4. Active learning of interatomic potentials to investigate thermodynamic and elastic properties of Ti0.5Al0.5N at elevated temperature

    Master-uppsats, Linköpings universitet/Teoretisk Fysik

    Författare :Florian Bock; [2021]
    Nyckelord :Thin Solid Films; TiAlN; Active Learning; MLIP;

    Sammanfattning : With the immense increase in the computational power available for the material science community in recent years, a range of new discoveries were made possible. Accurate investigations of large scale atomic systems, however, still come with an extremely high computational demand. LÄS MER

  7. 5. Wear mechanisms in austenitic stainless steel drilling : A comprehensive wear study

    Master-uppsats, KTH/Materialteknologi

    Författare :Alexander Dahlström; [2015]
    Nyckelord :Austenitic Stainless Steel; Cemented Carbide; Drilling; Wear mechanisms; Adhesive wear; Margin; Cracks.;

    Sammanfattning : This thesis is meant to serve as part of a competence platform for future product development projects at Sandvik Coromant AB, Solid Round Tools Department, Västberga, Sweden. The project objective is to gain generic knowledge of the wear mechanisms that restrict tool lifetime when drilling austenitic stainless steel. LÄS MER
