  1. 1. Influence of Post-treatments on Corrosion Properties of 3D printed Metal Components for Bioprocessing Applications

    University essay from KTH/Materialvetenskap

    Author : Leyla Koort; [2023]
    Keywords : PBF-LB 316L; surface post-treatments; as-built; tumbling; Hirtisation; DLyte; electropolishing; chemical milling; pitting corrosion; CPT; cyclic potentiodynamic polarisation curves; immersion test in 1M NaCl and 1M NaOH;

    Abstract : Additive manufacturing (AM) has the potential to overtake the conventional production of pipe systems of stainless steel grade 316L intended for bioprocessing applications by utilising powder bed fusion laser beam (PBF-LB) technologies. However, challenges such as high surface roughness need to be overcome and corrosion properties improved to meet industry standards. READ MORE

  3. 2. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance

    University essay from KTH/Materialvetenskap

    Author : Shunyi Li; [2022]
    Keywords : Super austenitic stainless steel; solid phase transformation; TTT diagram; impact toughness; critical pitting temperature; TC PRISMA simulation; Superaustenitiskt rostfritt stål; fastfasomvandling; TTT-diagram; slaghållfasthet; kritisk punktfrätningstemperatur; TC PRISMA simulering;

    Abstract : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.

  4. 3. Effekter av livsmedelsförädling för lokalkorrosion på rostfritt stål 316L

    University essay from Lunds universitet/Industriell Produktion

    Author : Fredrik Waldur; [2022]
    Keywords : Technology and Engineering;

    Abstract : Pitting corrosion on 316L stainless steel has been widely studied, but knowledge is lacking within food processing environments. A new test setup was developed to enable electrochemical measurements inside a heat exchanger (pasteurizer) where solutions can be heated and cooled rapidly, allowing for corrosion tests of solutions that do not withstand high temperatures for a long period of time.

  5. 4. Morphological and ageing studies of an electrolyte contaminated lithium-ion battery vent

    University essay from KTH/Kemiteknik

    Author : Bharathan Govindarajan; [2022]
    Keywords : Electrolyte; Battery vent; Ageing studies; Ageing model; Pitting corrosion; Elektrolyt; Batteriventil; Åldringsstudier; Åldringsmodell; Pitting-korrosion;

    Abstract : Undersökning av hur elektrolytkontamination på ventilen på prismatiska litiumjonbattericeller påverkar legeringsytan och påverkar batteriets säkerhet. Åldringsstudier utförs för att påskynda interaktionen av elektrolytförorenade batteriventiler vid önskade miljöförhållanden. READ MORE

  6. 5. Corrosion behavior of lead-free and dezincification resistant brass alloys in tap water

    University essay from KTH/Kemi

    Author : naza Alexis; [2021]
    Keywords : Corrosion; lead-free; brass; dezincification; electrochemistry; Korrosion; blyfri; mässing; avzinkning; elektrokemi;

    Abstract : Avzinkningshärdiga och blyfria mässingslegeringar används i stor utsträckning för att ersätta blyinnehållande mässingslegeringar som används för dricksvattensapplikationer. På grund av det begränsade antalet korrosionsstudier av dessa legeringar är syftet med denna studie att belysa hur vattensammansättning, temperatur och exponeringstid kan påverka legeringarnas korrosionsegenskaper.
