    The effect of coupling of unalloyed Mg and Mg-alloys (AZ91 and WE43) with Ti6Al4V alloy on corrosion and degradation behaviours of produced composites has been investigated in simulated body fluid (SBF) by hydrogen evolution, ...
  • Corrosion of Metallic Biomaterials 
    Dikici, Burak; Esen, Ziya; Duygulu, Özgür; Güngör, Serap (Springer Verlag, 2015)
    Metallic materials have been used as biomedical implants for various parts of the human body for many decades. The physiological environment (body fluid) is considered to be extremely corrosive to metallic surfaces; and ...
