Bone is among the most transplanted tissues for regeneration of bone defects, caused by trauma, age-related bone loss or bone infections. Due to their similar characteristics to the mineral phase of bone, calcium phosphates ...
Metastable austenitic stainless steels feature an abundance of different deformation mechanisms, which contribute to the distinguished mechanical properties of these alloys. However, these properties are known to depend ...
This thesis covers investigation of the surface phenomena of Ti-6Al-4V and Ti-6Al-2Sn-4Zr-2Mo alloys related with oxidation at elevated temperature and corrosion during chemical treatment in hydrofluoric-nitric acid (HF/HNO3) ...
This thesis assesses the influence of substrate surface integrity on different mechanical (flexural strength and contact damage resistance under spherical indentation) and tribological (scratch resistance as well as cracking ...
The presented work is a part of the ongoing effort on the development of high performance bio-based composites with enhanced durability, under static and dynamic mechanical loading including the exposure to elevated humidity. ...
Numerical and experimental simulation of engineering materials has been an emerging topic for recent decades. Reliable and efficient numerical simulations are only possible through correct and pragmatic modeling approaches. ...
Tetragonal polycrystalline zirconia stabilized with 3% mol of yttria (3Y-TZP) is a popular bioceramic, increasingly used for dental applications thanks to its good mechanical properties, biocompatibility and aesthetic ...
Hard coating 's thermal stability is essential due to the high temperature environment of high-speed cutting applications, while the induced phase and microstructure evolution affects the mechanical properties. In this ...
This study evolved to its last form primarily around the development of a hybrid material is the core of the work. This hybrid material is then further explored for two different applications which are catalysis and drug ...
Physical vapor deposited hard coatings comprised of cubic (c) transition metal (TM)-Al-N, and (TM)-Si-N are the current work horse materials for a large number of metal cutting and wear resistant applicatíons to light ...
The present dissertation is an in-depth investigation from the macro to atomic scale of industrial wear-resistant CVD hard coatings deposited on cemented carbides for cutting tool applications. Micro-compression tests at ...
Nowadays, cardiovascular diseases are mainly treated by implantation of a metallic or polymeric mesh, called stent, which maintains the artery widely open. This technique shows very good clinical results, however, it exists ...
In the last decades there has been growing interest in developing ceramic materials with high fracture toughness (Klc) and strength for structural applications. In the specific case of 3 mol% yttria-doped tetragonal zirconia ...
Plastic based materials are widely used for packaging applications. However, disposal of such petroleum-based materials e.g. polyethylene (PE) and polypropylene (PP) has become a huge threat to the environment due to its ...
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 ...
