  1. 21. Influence of the Processing Atmosphere on Binder Jetting of Stainless Steel: From Printing to Sintering

    Författare :Kai Zissel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbothermal Reduction; Powder Reusability; 17-4 PH; Oxidation; Binder Jetting; Debinding; Sintering; Additive Manufacturing; Processing Atmosphere; Stainless Steel;

    Sammanfattning : Binder Jetting (BJT) is considered a promising Additive Manufacutring (AM) technology for the production of complex metal components due to its high productivity and cost efficiency compared to other AM technologies. The BJT technology is a multi-step process that consists of printing, curing, depowdering, debinding and sintering. LÄS MER

  2. 22. Tribological behaviour of HVAF-sprayed WC-based coatings: : Role of process variables and binder chemistry

    Författare :Kaveh Torkashvand; Mohit Kumar Gupta; Shrikant V. Joshi; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribological Behaviour; HVAF; WC-Based Coatings; Process Variables; Binder Chemistry; Tribologisk Prestanda; HVAF; WC-baserade Beläggningar; Parametervariabler; Bindemedelskemi; Production Technology; Produktionsteknik;

    Sammanfattning : Tungsten carbide (WC) based metallic matrix coatings sprayed using high velocity air fuel (HVAF) technique have attracted increasing attention as they show excellent tribological performance in various wear conditions. In the HVAF method, particles’ in-flight temperature and velocity can be influenced by the process variables including nozzle configuration as well as feedstock particle size range. LÄS MER

  3. 23. Investigations of binder rejuvenation related to asphalt recycling

    Författare :Robert Karlsson; KTH; []
    Nyckelord :bitumen; rejuvenator; diffusion; ageing; aging; asphalt recycling; FTIR-ATR; RAP; structural stability; Hansen solubility parameters;

    Sammanfattning : Investigations described in this doctoral thesis concernmaterial behaviour related to asphalt recycling. More indetail, the thesis describes development and application ofmethods for characterisation of the rejuvenation process, inwhich old and new binders are mixed. LÄS MER

  4. 24. Insights into wear and deformation of alternative binder hardmetals

    Författare :Lisa Toller-Nordström; Susanne Norgren; Ben Britton; Uppsala universitet; []
    Nyckelord :hardmetal; cemented carbide; alternative binders; steel turning; electron microscopy; electron diffraction; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : This work presents new insights into how hardmetals with alternative binders as well as cobalt based references react to wear and deformation. The main focus has been on hardmetals for steel turning, but also on studying certain fundamental properties of the new binder materials. LÄS MER

  5. 25. Quantitative microscopy of coating uniformity

    Författare :Christina Dahlström; Tetsu Uesaka; Magnus Norgren; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating uniformity; coating microstructure uniformity; base sheet effects; argon ion beam milling; scanning electron microscopy; image analysis; binder distributions; autocorrelation analysis; random deposition process; simulation;

    Sammanfattning : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.
