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

    Master-uppsats, KTH/Materialvetenskap

    Författare :Leyla Koort; [2023]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Fredrik Waldur; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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.

  4. 3. Cooling Strategy Influence on Temperature in ETD Center

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Oskar Edinger; [2021]
    Nyckelord :Machining; Drilling; Exchangeable tip drill; 316L Stainless steel; Thermocouple; IR Thermography; Skärande bearbetning; Borrning; Löstoppsborr; 316L Rostfritt stål; Termoelement; IR Termografi;

    Sammanfattning : Striving for increased productivity while maintaining hole quality and high process robustness when drilling requires knowledge about the working principles of heat generation, mechanics and a proper cutting fluid that aids in cooling, lubricating and evacuating chips from the cutting zone. If the heat generated in the tool-workpiece and tool-chip interfaces does not exit the cutting zone adequately through the chips, the workpiece material or the redistribution of coolant the hole quality can be impacted negatively and breakdowns may occur which reduces overall productivity.

  5. 4. Influence of hydrogen on mechanical properties, microstructure and fracture surface of stainless steel 316L and stainless steel 304

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Mustafa Adnan Tawfeeq Salman; [2020]
    Nyckelord :Hydrogen embrittlement; stainless steel; microstructure; hydrogen charging; slow and fast strain rate.; Väteförsprödning; rostfritt stål; mikrostruktur; väte laddning; långsam och snabb töjnings hastighet;

    Sammanfattning : Since hydrogen is an alternative energy source and has both economic and environmental benefits, it has received more attention. To use hydrogen a certain condition must be met, safe pressurized containers which are often made of metal. The metal isrequired due to the high mechanical strength and reasonable cost. LÄS MER

  7. 5. Metal Filament 3D Printing of SS316L : Focusing on the printing process

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)
