  1. 1. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Johan Ranstad; [2023]
    Nyckelord :Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Sammanfattning : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. LÄS MER

  3. 2. In vitro study of Biodegradation in Mg-alloys by Isothermal Calorimetry

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Prasad Rajendra Kekare; Akshat Kulkarni; [2021]
    Nyckelord :Isothermal Calorimetry; Degradation of Mg Alloys; Supersaturated solid solution SSSS ; Corrosion rate; Aqueous corrosion.; Technology and Engineering;

    Sammanfattning : Magnesium corrosion in an aqueous environment is a multi-layer, complex process. A literature survey shows significant gaps and the modelling work reported indicates a lack of clarity in understanding the corrosion process. LÄS MER

  4. 3. Degradation of model biomedical Mg alloys in aqueous media

    Master-uppsats, Lunds universitet/Materialteknik

    Sammanfattning : This project investigates the influence of alloying elements, heat treatment and corrosion medium on the corrosion rates of three magnesium alloys Mg-5Zn, Mg0.27Ca, and Mg-0.27Ca-5Zn for use in bio-medical applications. LÄS MER

  5. 4. Investigation of the effect of alloying elements on the printability of biodegradable material

    Master-uppsats, KTH/Flerskalig materialmodellering

    Författare :Fikan Mubarok Rohimsyah; [2019]
    Nyckelord :;

    Sammanfattning : The integration of biodegradable implant into the human body must meet both engineering and physiological requirements. The properties of magnesium such as low density, high specific strength and other biocompatibility properties makes magnesium and its alloy suitable for several biodegradable implant application.
