1. Metal release from stainless steel and CoCrMo alloys in protein-rich environments – effects of protein aggregation, friction, and irradiation
Abstract : Highly corrosion-resistant alloys are used in sensitive environments such as the human body and food environments. However, even tiny amounts of released metals from these surfaces could potentially cause adverse effects. It is hence important to study the biointerface between corrosion-resistant alloys and protein-rich environments. READ MORE

2. Influence of carbides and nitrides on corrosion initiation of advanced alloys : A local probing study
Abstract : Advanced alloys often present precipitated carbides and nitrides in their microstructure following exposure to elevated temperatures. These secondary phases are usually undesirable, because potentially deleterious for the corrosion and mechanical performances of the material. READ MORE

3. Silicon nitride for total hip replacements
Abstract : For more than 50 years total hip replacements have been a common and successful procedure to increase patient mobility and quality of life. The 10-year implant survival rate is 97.8%. READ MORE

4. Investigation of the corrosion and tribocorrosion behaviour of metallic biomaterials
Abstract : Metals are commonly used in various biomedical applications due to their excellent mechanical properties, such as high strength, ductility and toughness.However, the main drawback of metallic biomaterials is their high reactivity, which makes them especially susceptible to corrosion when exposed to aqueous environments such as body fluids.

5. Time dependent flow of biolubricant and suspended particles behavior within total hip replacement
Abstract : Total hip replacement (THR) has been one of the most successful surgeries in the 21st century. Ultra-high-molecular-weight-polyethylene (UHMWPE) shows favorable mechanical and tribological properties when used as a bearing surface material in THR. However, produced UHMWPE wear particles challenge increasing the THR lifetimes. READ MORE
