Isothermal hot compression tests of two promising new titanium alloys (Ti-10 V-1Fe-3Al and Ti-10 V-2Cr-3Al) are performed using a TA DIL805D deformation dilatometer at temperatures in and above the two-phase α + β region (730–880 °C) at strain rates ranging from 10<sup>−3</sup> to 10<sup>−1</sup> s<sup>−1</sup>. Results show that the flow...

In this study, different surface pretreatments were applied to clean and activate titanium alloy surfaces. The samples were subjected to grit blasting treatments using two different pressures and afterwards, a UV/Ozone treatment was applied at different times to study the wettability and surface oxidation of the titanium samples. Scanning...

This work introduces a novel nanocomposite coating with dual-action self-healing corrosion protection activated by the photothermal response of plasmonic titanium nitride nanoparticles (TiN NPs). TiN@mesoporous SiO<sub>2</sub> core–shell nanocontainers were developed as reservoirs for benzotriazole (BTA) corrosion inhibitors and incorporated...

A cold-rolled Ti-V high strength low alloy (HSLA) steel was isothermally annealed at 650 °C and 700 °C for different times. A unique combination of techniques including visible light microscopy (VLM), transmission electron microscopy (TEM), matrix dissolution, small angle neutron scattering (SANS) and hardness measurement has been employed to...

Additively manufactured (AM) porous metallic biomaterials, in general, and AM porous titanium, in particular, have recently emerged as promising candidates for bone substitution. The porous design of such materials allows for mimicking the elastic mechanical properties of native bone tissue and showed to be effective in improving bone...

The anodization of commercially pure Ti alloy (99.5 wt %) and two biomedical titanium alloys, Ti6Al7Nb and Ti6Al4V, was performed, and the resulting anodic oxides were studied. The biomedical alloys were made by Laser Engineered Net Shaping. The glycol-based and glycerol-based electrolytes with 0.3 M ammonium fluoride and 2 wt % of deionized...

In this paper, laser powder-bed fusion (L-PBF) additive manufacturing (AM) with a high-temperature inductive platform preheating was used to fabricate intermetallic TiAl-alloy samples. The gas atomized (GA) and mechanically alloyed plasma spheroidized (MAPS) powders of the Ti-48Al-2Cr-2Nb (at. %) alloy were used as the feedstock material. The...

Additive Manufacturing (AM) is an attractive way of producing parts of intermetallic titanium alloys. However, high brittleness of these alloys makes it challenging to produce crack-free intermetallic parts by AM. One way to overcome this problem is to use high-temperature powder-bed preheating. In this paper, Ti-48Al-2Cr-2Nb alloy was...

Multi-pass-dual-indenter (MPDI) scratch tests with various loading conditions were performed on two newly developed titanium alloys (Ti–10V–1Fe–3Al and Ti–10V–2Cr–3Al) to investigate their abrasion resistance under repetitive local sliding contact. A technically pure titanium sample was used as the reference. Various microstructures were...

Background. The past four decades, the problem of resistant bacteria has emerged. As a result of biofilm formation of (resistant) bacteria on the implant, more implant-associated infections (IAI) occurred. This has caused an increase in orthopaedic implant revisions, causing a high burden of disease. To overcome the rising problem of resistance,...

Degenerative disc disorders are among the most commonly diagnosed conditions and the leading cause for back and neck pain, affecting more than 266 million individuals annually. Interbody fusion is the proposed surgical treatment whenever lighter approaches such as physiotherapy and painkillers fail to improve the patient’s condition. It consists...

In the competitive road race-cycling sport, having a frame that is lighter and aerodynamic, grants a competitive advantage. If we look at the market, the lighter and expensive bicycles are made from carbon where the cheaper models are made out of metal-alloys. This makes the consumer biased towards metal-alloy frames, mostly about the weight. To...

Implant associated infections are one of the main reasons for implant failure in total joint arthroplasty. The cause is due to bacteria that adhere to surfaces forming a biofilm. Biofilm formation is an irreversible situation which requires excessive hospitalization and medical treatment with antibiotics, however bacteria have been proven highly...

BACKGROUND.Implant-associated infection (IAI) is a rising complication in bone-related medical treatments using metal implants. Preventive measures, such as implant surfaces with integrated antibacterial properties, are hence required. The emergence of antibiotic-resistant pathogens has led to a growing interest in inorganic nanoparticles as...

In this thesis, a methodology is developed that allows for both reliable and computational efficient robustness analysis of aircraft component distortion. This research applies to dis- tortion caused by reductive manufacturing processes that are used to obtain monolithic components from pre-stressed stock material. With the developed methodology...

Optical trapping of (sub)micron-sized particles is broadly employed in nanoscience and engineering. The materials commonly employed for these particles, however, have physical properties that limit the transfer of linear or angular momentum (or both). This reduces the magnitude of forces and torques, and the spatiotemporal resolution,...

A challenge in developing an in-depth understanding of the crack growth resistance of Additively Manufactured materials is the fact that their mechanical properties have been shown to be both process and part-geometry dependent. Up to now, no studies have investigated the influence of off-axis (beyond the three orthogonal build orientations)...

In the current day and age, osteogenic bone implants are important to reduce healing time and infections after bone implantation. To help induce bone formation, the implant surface can be biofunctionalized with different agents. A promising surface modification technique used to treat titanium implants is Plasma Electrolytic Oxidation (PEO). In...

The emergence of antibiotic-resistant bacteria has increased the number of implant revision procedures in the Netherlands due to implant-associated infections (IAI). Staphylococci strains accounted for more than 50% of all IAI cases. Preventative measure, such as active antibacterial surfaces on the implant, are urgently needed. This study aims...

Massive acetabular bone defects are difficult to treat with the currently available implants. Advances in additive manufacturing create new design possibilities, which allow the production of patient specific implants. These endless possibilities will enable to tune the mechanical properties of porous implants and to distribute the loads in such...
