  1. 1. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Ulrike Küst; [2023]
    Keywords : APXPS; catalysis; palladium; methane; Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. READ MORE

  3. 2. Influence of hydrogen and carbides on high temperature cracking in cast Inconel

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Gunnar Dufwa; [2022]
    Keywords : Hydrogen embrittlement; carbide; finite element method; dislocation dynamics;

    Abstract : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. READ MORE

  4. 3. Investigation of robustness of a SiC MOMS pressure sensor in high pressure/temperature operation conditions

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Monika Sieczka; [2022]
    Keywords : ;

    Abstract : Rigorous environmental policies and the need for higher fuel economy continuously demand new innovations in the combustion process of automotive engines. Consequently, there is an increasing necessity for active monitoring of the combustion event, and therefore, microsystems have started coming into play. READ MORE

  5. 4. Evaluation of a novel method to investigate diffusion between copper-zinc alloys and cemented carbides

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : André Larsson; [2022]
    Keywords : Diffusion; Brass; Copper alloys; Copper zinc alloys; Wear; Cemented carbide; Diffusion couple;

    Abstract : When slow wear mechanisms are studied it is important to examine slower processes, such as diffusion. Such processes can have a significant impact over time and can cause other phases to form, which can have a large effect on the wear. READ MORE

  6. 5. Evaluation of Refined Tribological Properties of Diamond Coated Cutting Tools Used in Machining of High-Strength Aluminum Alloys : Master thesis report regarding refined frictional & wear behavior of uncoated & CVD diamond coated WC-Co cemented carbide cutting tools used for machining of Al 7xxx alloys.

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Christian Hultman; [2022]
    Keywords : tribology; machining; metal cutting; turning; milling; friction; wear; material transfer; surface technology; tribologi; skärande bearbetning; svarvning; fräsning; friktion; förslitning; nötning; materialöverföring; ytteknologi;

    Abstract : High strength aluminum alloys have for a long time been a popular material utilized in the automotive and aerospace sector due to coveted mechanical properties in terms of weight, strength, fatigue, and corrosion. However, tribological mechanisms such as tribo-film formation and material transfer during the metal cutting manufacturing process of aluminum impose significant reduction of machining and tool-life performance.
