    Author : Wei Zheng; [2017]
    Keywords : CoCrMo alloy; metal release; corrosion resistance; albumin; fibrinogen;

    Abstract : Corrosion and metal release mechanisms of CoCrMo alloys are at human biological conditions not fully understood. The main objective of this master thesis was to investigate whether the Vroman effect influences the extent of metal release from CoCrMo alloy in mixed protein solutions. READ MORE

  5. 4. Model test for fabrication and separation of wear particles in hip implants

    University essay from Tillämpad materialvetenskap

    Author : Charlotte Skjöldebrand; [2013]
    Keywords : hip implant; model test; wear particles; silicon nitride;

    Abstract : Total hip replacement is a common orthopedic surgery today with a population with an increasing life expectancy and a more active lifestyle. Most implants have a life expectancy of 10 years or longer, however after 25 years one out of four implants has been revised. This means that the risk of a secondary surgery is high for young patients. READ MORE
