  1. 1. New design and construction of hightemperature tribology testingequipment : in the context of hard coatings

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

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

    Abstract : 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. READ MORE

  3. 2. Material analysis for a rotating inlet valve : Sliding contact in an oil-free super-critical steam environment

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johan Samuelsson; [2022]
    Keywords : Mechanical carbon; graphite; carbon graphite; zirconia; steam engine; steam; tribology; friction; wear; stellite; nitronic 60; antimony; carbon; Ni-resist cast iron; waste heat recovery; rotating inlet valve; valve; Mekaniskt kol; gafit; ångmotor; ånga; tribologi; friktion; nötning; gjutjärn; roterande inloppsventil; ventil;

    Abstract : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. READ MORE

  4. 3. Tribolysis : – Reaction of Aromatic Halides for Potential Dehalogenation

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

  6. 5. Tribological characterization of selected hard coatings

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Patrik Karlsson; [2009]
    Keywords : Tribology;

    Abstract : Hard coatings are often used for protection of tool surfaces due to coating properties like low friction and high wear resistance. Even though many of the hard coatings have been tested for wear, it is important to try new wear test setups to fully understand tribological mechanisms and the potential of hard coatings. READ MORE
