  1. 1. A pre-study for functional coatings evaluated on light metals to be applied on a new HPDC Mg-alloy : Investigating tribological and thermophysical properties, as-cast and coated

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Louise Albo Zieme; Pontus Bergstedt; [2021]
    Keywords : reciprocating dry sliding wear test; thermophysical test; NiP-SiC; Ni-SiC; functional coatings; progressive scratch test; adhesion; magnesium alloy; aluminium alloy; hardness.;

    Abstract : Magnesium with two-thirds of the density compared to aluminium and one-quarter of steel, intrigues product developers and material scientists due to the light metal’s excellent combination of strength to weight ratio as well as their capability of being produced as a High Pressure Die Cast component compared to other ferrous or light metal alloys.   However, a magnesium alloy inherits some concerning drawbacks, limiting the exploitation in structural applications and mechanical design such as automotive, heavy machinery and aerospace components.

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

    University essay from Uppsala universitet/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
