  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. Tribological behaviour of CVD diamondcoated tools during machining of highstrength aluminum alloy : Master thesis project on tribological behavior of super hard materials: chemicalvapor deposition diamond (CVD) coated cutting tools and polycrystalline diamond(PCD) cutting tools used in machining of high strength aluminium alloy

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

    Author : Oskar Lundquist; [2022]
    Keywords : CVD diamond coating; CVD; Aluminum machining; Tool coatings; PCD; diamond coating; diamond; Tribology; Material Science.;

    Abstract : Machining of Aluminum can be complicated due to large amounts of adhesion and diffusion of the aluminum onto the cutting tool, causing effects such as built-up layers and built-up edges. This leads to poor surface finishes and can significantly affect the tool life. READ MORE

  4. 3. Stretchable Barrier Coatings For Fiber-Based Materials : A laboratory study into the development of extensible/stretchable barrier coatings with nanoclay implementation, focusing on water vapour barrier properties.

    University essay from Karlstads universitet

    Author : Kajin Muradparist; [2021]
    Keywords : Stretchable; Barrier; Coating; WVTR; WVP; Hydroforming; Töjbar; Barriär; Bestrykning; WVTR; WVP; Hydroforming;

    Abstract : Executive summary Today, packaging has gained a significant role in the food industry as well as other industries. Paper substrates that have been coated in some ways are typically used to make packaging. The amount and type of pigment used in the formulation determine whether this coating is a pigment coating or a barrier coating. READ MORE

  5. 4. Chemical Vapor Deposition of Titanium Oxycarbide

    University essay from Lunds universitet/Industriell Produktion

    Author : Carl Henrik Dahmén; [2020]
    Keywords : CVD; Hard Coatings; Ti C; O ; CO; Five-ling twinned crystals.; Technology and Engineering;

    Abstract : Ti(C,O) coatings have been generated in a hot wall CVD system on WC/Co, fine and coarse grained Ti(C,N), TiN, Cr and c-BN substrates. The research in this thesis has focused on deposition, characterization, and analysis in the perspective of the bonding layer of a coated insert. READ MORE

  6. 5. Evaluating the interaction between CC-studs and pavement

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Elias Helou; [2019]
    Keywords : ;

    Abstract : Studded tyres are used in many countries around the world. Excessive wear of the road is the result when using studded tyres, and thus time of usage is limited or prohibited. A stud consists of a hard metal part enclosed in steel, aluminium, plastic or rubber, which is anchored in the tyre. READ MORE
