  1. 1. Atomic wear mechanisms of hard chrome against Al2O3

    M1-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Raul Fierro Tobar; Marius Yuku; [2021]
    Nyckelord :Wear mechanisms; DFT; MD; hard chrome; aluminium; RDF; adhesive; abrasive; Nötning; DFT; MD; hårdkrom; aluminium; RDF; adhesiv; abrasiv;

    Sammanfattning : Hard chrome exhibit hardness of about 70 HRC and lubricity that prevents seizing and galling and is therefore the common first choice for engineers to reduce friction and minimize wear. These properties enable engineering applications such as cutting and drilling, especially in manufacturing, production and consumer good industries. LÄS MER

  3. 2. Quality perception study in sustainable materials for Volvo Cars

    Master-uppsats, Jönköping University/JTH, Industridesign

    Författare :Irene Ramos; [2021]
    Nyckelord :Affective engineering; Kansei engineering; User experience; User study; Quality perception; Customer appreciations; Sensory evaluation; Neuroaesthetic; Car interior design; Sustainable materials; Chrome surface; Chrome appearance; Chrome Plating; Hexavalent chromium; Soft metrology; Material experience; Material meanings; Visual appearance;

    Sammanfattning : The growing demand in the industry towards sustainability and the globalization of manufacturing lead to an industrial climate of constant development and improvements, and automotive interior design is not excluded. In 2017 the European Union declared that the material used to generate the bright chrome surfaces of car interiors (CR VI) is toxic and carcinogenic. LÄS MER

  4. 3. Ett hållbart läder : En jämförande studie mellan konventionellt läder och naturmaterialet Piñatex

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Klara Bryntesson; Cajsa Ferling; [2019]
    Nyckelord :Piñatex; leather; vegetable tanning; chrome tanning; leather process; Piñatex; läder; vegetabilisk garvning; kromgarvning; läderprocess;

    Sammanfattning : Läder som material har använts av människor i århundraden och är ett av de mest tåliga materialen som finns idag. Detta leder till att det produceras extremt höga mängder läder där den högsta andelen som produceras är kromgarvat läder, som står för cirka 90 procent av den totala läderproduktionen. LÄS MER

  5. 4. The Magnetic Characterization of Iron-Chrome nanoparticle

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Angga Virdian; [2018]
    Nyckelord :Nanomagnetism; Nanoparticle; Physics and Astronomy;

    Sammanfattning : In this thesis, the intrinsic magnetic characteristic of 10 nm FeCr oxide nanoparticles is studied. The nanoparticles is produced using the method of Spark discharge generation. Scanning electron microscope (SEM) is used to characterize the size distribution and coverage of deposited particle. LÄS MER

  7. 5. Sliding wear performance of electroplated hard chromium and autocatalytic nickel-phosphorus coatings at elevated temperatures

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

    Författare :Mats Eriksson; [2014]
    Nyckelord :Tribology; sliding wear; hard chrome; electroless nickel;

    Sammanfattning : This thesis was written for a Swedish valve manufacturer to find out in what temperature regimes it was possible to replace electroplated hard chromium with autocatalytic electroless nickel-phosphorus. In this work the dry sliding wear properties of electroplated hard chromium and autocatalytic electroless nickel-phosphorus(10% P) were compared. LÄS MER
