    Keywords : Alpha-iron; Chromium carbide; Cr7C3; Fe; Theoretical investigation; Orthorhombic; X-ray diffraction pattern; XRD; VASP; VESTA; Body-centered-cubic; Ferrite; Density functional theory; DFT; Surface relaxation; Simulation; Calculation; Energy relaxation; Slab models; Coherency; Surface energy; Interfacial energy; Alfa-järn; Kromkarbid; Cr7C3; Fe; Teoretisk undersökning; Ortorombisk; Röntgendiffraktion; XRD; VASP; VESTA; Ytenergi; Koherent; Simulering; Beräkning; Järnkarbid; DFT; Täthetsfunktionalanalys;

    Abstract : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). READ MORE

  3. 2. Development of a Method to Predict the Adhesion of Industrial Paint Coating

    University essay from KTH/Fiber- och polymerteknologi

    Author : Akheen Sadik; [2022]
    Keywords : Contact angle technique; optical tensiometer; paint coating; adhesion promoter; silane; kontaktvinkel; optisk tensiometer; ytbehandling; adhesion; silan;

    Abstract : I samarbete med Sherwin-Williams AB, utvecklades en metod med kontaktvinkelmätning för att teoretiskt uppskatta vätbarhet och vidhäftningsförmåga av industriella färger på stålsubstrat. Optisk tensiometer och Youngs ekvation kombinerat med OWRK beräkningsmodell användes för att bestämma ytenergier. READ MORE

  4. 3. Modelling of precipitation in an Fe-C-Cr alloy

    University essay from KTH/Materialvetenskap

    Author : Johan Frisk; [2019]
    Keywords : ;

    Abstract : Precipitation modelling is interesting from both an academic and an industrial point of view. Such modelling tools may be used in the field of integrated computational materials engineering (ICME) for design and optimization of material properties. READ MORE

  5. 4. Towards omnimaterial printing : Expanding the material palette of acoustophoretic printing

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Jacob Kjellman; [2019]
    Keywords : Acoustophoretic printing; Drop on Demand; Superamphiphobic nozzle; Surface functionalization; Coating; Candle soot template;

    Abstract : Dropp-genereringstekniker är viktiga för industrier som läkemedelsindustrin, livsmedelsindustrin, kosmetikindustrin etc. Traditionella droppgenereringstekniker är dock begränsade i mängden av material som kan processas till droppform. READ MORE

  6. 5. A Study of Various Parameters Affecting Adhesion of Coatings to Metal Substrates

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)
