  1. 1. Application of copper corrosion inhibitors in mineral oil : Surface analytical studies and corrosion mitigation evaluations

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Martina Levin; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This doctoral thesis explores the copper corrosion inhibiting properties of a number of nitrogen containing hetero-organic compounds in refined mineral oil. Traditional organic corrosion inhibitors, as well as novel and bioorganic compounds have been studied. READ MORE

  2. 2. Strain-assisted corrosion cracking and growth rate inhibitors

    University dissertation from Andrey Jivkov, Solid Mechanics, Malmö University, SE-205 06 Malmö, Sweden

    Author : Andrey P Jivkov; Lunds universitet.; Lund University.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; materialteknik; Mechanical engineering; Material technology; Materiallära; Stress intensity factor; Inhomogeneous materials; Crack evolution; Stress corrosion cracking; Moving boundary; hydraulics;

    Abstract : A model for evolution of cracks as a result of strain-assisted corrosion is presented. The considered cracks possess a realistic geometry, where the tip region is an integral part of the crack surface instead of being a singular point. This geometry is either implicitly defined or is a consequence of crack nucleation from surface irregularities. READ MORE

  3. 3. The Mussel Adhesive Protein (Mefp-1) A GREEN Corrosion Inhibitor

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Fan Zhang; KTH.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon steel; mussel adhesive protein; Mefp-1; inhibitor; adsorption; film forming; complexation; cross-linking; ceria nanoparticle; composite film; EIS; AFM; QCM-D; ATR-FTIR; Confocal Raman Micro-spectroscopy; DFT calculation;

    Abstract : Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. READ MORE

  4. 4. Novel boron compounds in lubrication

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mamoun Taher; Luleå tekniska universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Lubricants are used to control friction and reduce wear by preventing direct contact between surfaces in a relative motion. Most of the modern lubricants and lubricant additives have been designed and optimized for ferrous materials. READ MORE

  5. 5. Boron compounds as additives to lubricants synthesis, characterization and tribological optimization

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Faiz Ullah Shah; Luleå tekniska universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Natural sciences - Chemistry; Naturvetenskap - Kemi; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Developing new technological solutions, such as use of lightweight materials, less harmful fuels, controlled fuel combustion processes or more efficient exhaust gas after-treatment, are possible ways to reduce the environmental impact of machines. Both the reduction of wear and the friction control are key issues for decreasing of energy losses, improving efficiency and increasing of the life-span of an engine. READ MORE
