  1. 1. Influence of nitrocarburization on the thermomechanical fatigue properties of ductile iron for exhaust components : Analysis and comparisons of TMF-properties

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

    Author : Karl Larsson; [2019]
    Keywords : Thermo-mechanical fatigue; low cycle fatigue; thermal strain; ductile cast iron; nitrocarburizing;

    Abstract : New stricter environmental legislation requires lower emissions and fuel consumption of automotive engines. Therefore the fuel efficiency must be increased but this leads to higher loads in the engine. As for the exhaust system it is affected by higher thermomechanical loads. READ MORE

  2. 2. Influence of Nitrocarburization on Thermo-Mechanical Fatigue Properties : Material Characterization of Ductile Cast Iron for Exhaust Components

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

    Author : Wännman Sofia; [2018]
    Keywords : Ductile cast iron; Nitrocarburizing; Thermo-mechanical fatigue;

    Abstract : The large number of vehicles operating on the roads cause high emissions and consequently a negative effect on the environment. When developing and optimizing internal combustion engines, certain requirements must be considered, which are environmental regulations, reduced fuel consumption and increased specific power.

  3. 3. Nitrocarburizing and High Temperature Nitriding of Steels in Bearing Applications

    University essay from Chalmers tekniska högskola/Institutionen för material- och tillverkningsteknik

    Author : Isabella Flodström; [2012]
    Keywords : ferritic nitrocarburizing; austenitic nitrocarburizing; solution nitriding; bearing steel; stainless steel; heat resistant steel;

    Abstract : A group of steels used in bearing applications were subjected to three different heat treatments – gaseous ferritic and austenitic nitrocarburizing at 580 °C and 620 °C respectively and solution nitriding at 1100 °C. The aim was to improve wear and corrosion resistance of the steels and to evaluate for which steels the processes are most suitable. READ MORE

  4. 4. Evaluation of Journal Bearings in Manual Transmissions

    University essay from MaskinkonstruktionInstitutionen för ekonomisk och industriell utveckling; MaskinkonstruktionInstitutionen för ekonomisk och industriell utveckling

    Author : Joachim Vidar; Jonas Mellstedt; [2009]
    Keywords : journal bearing; manual transmission; efficiency; wear; gearbox;

    Abstract : This thesis work is an evaluation of journal bearings in manual transmissions in automobiles. Today both journal- and needle bearings can be positioned into the gearboxes and in order to reduce the power loss developed by friction when a relative angular velocity arises, the right type of bearing must be chosen.
