  1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Shivang Parmar; [2023]
    Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

    Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE

  3. 2. Maximum Inverter AC Current Prediction Based on Junction Temperature Calculation

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

    Author : Shuyu Ou; [2019]
    Keywords : IGBT; Inverter; Junction temperature; Current Limiter; IGBT; Växelriktare; Övergångstemperatur; Strömbegränsare;

    Abstract : Semiconductor devices are widely used in the automotive industry, and they are key components of the inverter and the converter in an electric vehicle. Thus, the concern of protecting the inverter and the converter from damaging operation has been raised. The junction temperature is one of the main considerations. READ MORE

  4. 3. Thermal fatigue and soldering experiments of additively manufactured hot work tool steels

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

    Author : Henrik Andersson; [2018]
    Keywords : Additive manufacturing; 3D printing; Hot work tool steel; Thermal fatigue; heat checking; Die casting; Soldering; AISI H13; Additiv tillverkning; 3D printing; Varmarbetsstål; Termisk utmattning; Värmesprickor; Pressgjutning; Soldering; AISI H13;

    Abstract : Modern manufacturing processes are under a never ending evolvement. Lowered manufacturing costs, higher part quality, shorter lead times and lower environmental impact are some important drivers for this development. Aluminum die casting is an effective and attractive process when producing components for e.g. READ MORE

  5. 4. Bengtsson_Magnusson_Durability of construction solutions with fiber-reinforced polymers (FRP) in pedestrian bridges

    University essay from Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Author : David Bengtsson; Tommy Magnusson; [2016]
    Keywords : FRP; Friber-reinforced polymer; durability; environmental impact; weathering; composites; civil engineering;

    Abstract : Arbetet har genomförts i samarbete med Malmö Gatukontor med målet att samla in information om fiberförstärkta plastkompositer (fiber-reinforced polymer; FRP). FRP-kompositer kan vara ett intressant alternativ till konventionella byggnadsmaterial på grund av sina goda materialegenskaper. READ MORE

  6. 5. Thermo-mechanical fatigue of castiron for engine applications

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Niklas Collin; [2014]
    Keywords : Thermo-mechanical fatigue; TMF; CGI; LGI; fatigue; thermal strain.; Termomekanisk utmattning; TMF; CGI; LGI; termisk töjning.;

    Abstract : In an engine component the repeated start-stop cycles cause temporal and local inhomogeneous temperatures, which in turn lead to a type of low-frequency loading, plastic deformation and eventually failure due to thermo-mechanical fatigue. Simultaneously, high-frequency mechanical loading arises from the cyclic combustion pressure and from road induced vibrations. READ MORE
