  1. 1. Erosion of materials in centrifugal separation

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Alexander Hillström; [2022]
    Keywords : Solid particle erosion; Erosion mechanism; Erosion testing;

    Abstract : Centrifugal separation is a crucial piece of technology, used in a wide range of industries. In cases where solid particles are included in the working medium, erosive wear of componentsinside a centrifugal separator is one of the reasons limiting its service life. READ MORE

  2. 2. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings

    Abstract : The topic of osmund iron is of great interest in both historical and metallurgical perspective. Between the 14th and the 17th century osmund iron was exported extensively from Sweden but it has been difficult to characterize and confirm what exactly osmund iron is. READ MORE

  5. 5. Investigation of non-metallic inclusions and chip properties in Cu-based alloys by numerical analysis

    University essay from KTH/Materialvetenskap

    Author : Ousmane El Hamid; Mattias Eriksson; [2022]
    Keywords : ;

    Abstract : Analysis of the macrostructure of metallic alloys is of utmost importance as there is a direct correlation on the physical properties and some features of the structures. This is true for copper based alloys and the non-metallic inclusions (NMI) that are enclosed in their structure. READ MORE
