  1. 1. Quality Management during Sintering of Cemented Carbides and Cermets

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :Josefin Sipola; [2015]
    Nyckelord :Sintering; Cemented Carbides; Cermets; Coercivity; weight-specific magnetic saturation; CoM;

    Sammanfattning : The magnetic properties, coercivity, Hc, and weight-specific magnetic saturation, CoM, are two important quality characteristics in cemented carbides and ceramic metals, cermets. These properties give information about grain size and binder phase content, and are influenced by the different stages in the sintering process. LÄS MER

  2. 2. Controlling Co-capping in sintering of cermets

    Uppsats för yrkesexamina på avancerad nivå, Oorganisk kemi

    Författare :Sven Englund; [2013]
    Nyckelord :Cermet; Co-capping; sintering;

    Sammanfattning : This master thesis includes a literature study and experimental work to understandthe conditions where a binder phase layer, Co-capping, could be produced orinhibited, for three different cermet grades in order to suggest changes in thesintering processes and two production units. The effect of C activity and sinteringatmosphere, e.g. LÄS MER

  3. 3. Characterization of Hard Metal Surfaces after Various Surface Process Treatments

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Ali Hakim; [2008]
    Nyckelord :WC-Co; cermet; grinding; blasting; polishing; residual stress; surface roughness; surface deformations; cross section; adhesion;

    Sammanfattning : The aim of this thesis is to investigate how material surfaces are affected by various surface treatments and how this relates to the adhesion of the coating. The materials that were studied were WC-Co and Cermets and the surface treatments used were polishing, grinding with coarser and finer abrasive grains, and finally wet blasting and dry blasting.
