  1. 1. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kaibin Wen; [2023]
    Keywords : Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

    Abstract : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. READ MORE

  2. 2. 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. 3. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hamidreza Rastan; [2019]
    Keywords : Minichannel; Microchannel; Heat exchanger; Additive manufacturing; 3D printing; Numerical simulation; CFD; Comsol;

    Abstract : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.

  4. 4. Evaluation of alternative methods forquality control of Tungsten Carbide : An evaluation of four different particle measuring techniques

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Markus Näsman; [2019]
    Keywords : Particle measurement; Quality control; Tungsten Carbide; Hard metal; Fisher Sub-Sieve Sizer; Brunauer Emmett Teller; X-ray Diffraction; Laser Diffraction;

    Abstract : The purpose of this study was to evaluate four different measuring methods as potentialquality control tests for Tungsten Carbide (WC) raw material used in the hard metalmanufacturing at Seco Tools Fagersta. This was warranted as the current quality testcalled the HcK test, is very time consuming and the results provided that are used formilling time calculations cannot be relied on. READ MORE

  5. 5. Business Case - Implementation of Laser Technologies at Scania Ferruform : Welding- and cutting applications for the manufacturing of banjo parts

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Markus Hedemalm; Zebastian Hallsten; [2018]
    Keywords : Laser material processing; Laser welding; Laser arc hybrid welding; Laser cutting;

    Abstract : Scania Ferruform AB is an independent affiliate of the truck- and bus manufacturer Scania AB which produces rear axle housings among other chassis components for said vehicles. The banjo part, i.e. READ MORE
