An investigation into corrosion inhibition properties of a primer coating containing lithium carbonate as corrosion inhibitive pigment for AA2024 aluminum alloy was conducted. It was found that, during neutral salt spray exposure, a protective film of about 0.2 to 1.5 ?m thickness formed within the area where an artificial defect was introduced...

Forming of magnesium alloy microtubes in the fabrication of biodegradable stents

Wang, L. (author), Fang, G. (author), Qian, L. (author), Leeflang, M.A. (author), Duszczyk, J. (author), Zhou, J. (author)

Magnesium alloys have, in recent years, been recognized as highly promising biodegradable materials, especially for vascular stent applications. Forming of magnesium alloys into high-precision thin-wall tubes has however presented a technological barrier in the fabrication of vascular stents, because of the poor workability of magnesium at room...

Influence of HEPES buffer on the local pH and formation of surface layer during in vitro degradation tests of magnesium in DMEM

Naddaf Dezfuli, S. (author), Huan, Z. (author), Mol, J.M.C. (author), Leeflang, M.A. (author), Chang, J. (author), Zhou, J. (author)

The human body is a buffered environment where pH is effectively maintained. HEPES is a biological buffer often used to mimic the buffering activity of the body in in vitro studies on the degradation behavior of magnesium. However, the influence of HEPES on the degradation behavior of magnesium in the DMEM pseudo-physiological solution has not...

Fabrication of metallic biomedical scaffolds with the space holder method: A review

Arifvianto, B. (author), Zhou, J. (author)

Bone tissue engineering has been increasingly studied as an alternative approach to bone defect reconstruction. In this approach, new bone cells are stimulated to grow and heal the defect with the aid of a scaffold that serves as a medium for bone cell formation and growth. Scaffolds made of metallic materials have preferably been chosen for...

The effect of SiC particle size on the healing efficiency of alumina at high temperatures

Boatemaa, L. (author), Zhou, J. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)

Structural ceramics like alumina are usually brittle and sensitive to flaws leading to a reduction in their mechanical properties. This situation is worsened by machining prior to service and during service by contact, which introduces micro cracks and hidden damages. Crack damage can easily be developed in such ceramics when loaded, which often...

Effect of the size distribution of nanoscale dispersed particles on the Zener drag pressure

Eivani, A.R. (author), Valipour, S. (author), Ahmed, H. (author), Zhou, J. (author), Duszczyk, J. (author)

In this article, a new relationship for the calculation of the Zener drag pressure is described in which the effect of the size distribution of nanoscale dispersed particles is taken into account, in addition to particle radius and volume fraction, which have been incorporated in the existing relationships. Microstructural observations indicated...

Magnesium-based composites with improved in vitro surface biocompatibility

Huan, Z. (author), Zhou, J. (author), Duszczyk, J. (author)

In this study, bioactive glass (BG, 45S5) particles were added to a biodegradable magnesium alloy(ZK30) through a semi-solid high-pressure casting process in order to improve the surface biocompatibility of the biomaterial and potentially its bioactivity. The observation of the as-cast microstructures of ZK30-BG composites indicated homogeneous...

In vitro degradation behavior and cytocompatibility of Mg–Zn–Zr alloys

Huan, Z.G. (author), Leeflang, M.A. (author), Zhou, J. (author), Fratila-Apachitei, L.E. (author), Duszczyk, J. (author)

Zinc and zirconium were selected as the alloying elements in biodegradable magnesium alloys, considering their strengthening effect and good biocompatibility. The degradation rate, hydrogen evolution, ion release, surface layer and in vitro cytotoxicity of two Mg–Zn–Zr alloys, i.e. ZK30 and ZK60, and a WE-type alloy (Mg–Y–RE–Zr) were...

Low-temperature fabrication of macroporous scaffolds through foaming and hydration of tricalcium silicate paste and their bioactivity

Huan, Z. (author), Chang, J. (author), Zhou, J. (author)

A low-temperature fabrication method for highly porous bioactive scaffolds was developed. The two-step method involved the foaming of tricalcium silicate cement paste and hydration to form calcium silicate hydrate and calcium hydroxide. Scaffolds with a combination of interconnected macro- and micro-sized pores were fabricated by making use of...

Correlation between Electrical Resistivity, Particle Dissolution, Precipitation of Dispersoids, and Recrystallization Behavior of AA7020 Aluminum Alloy

Eivani, A.R. (author), Ahmed, H. (author), Zhou, J. (author), Duszczyk, J. (author)

This research concerns the effect of homogenization treatment on the electrical resistivity of AA7020 aluminum alloy variants with different Zr and Cr contents. Small changes in the Zr and Cr contents of the as-cast alloy increase the electrical resistivity significantly. After employing various homogenization treatments, the electrical...

Evolution of Grain Boundary Phases during the Homogenization of AA7020 Aluminum Alloy

Eivani, A.R. (author), Ahmed, H. (author), Zhou, J. (author), Duszczyk, J. (author)

The presence of large constitutive particles formed during solidification decreases the strength and hot workability of aluminum alloys especially when they are located in the grain boundary (GB) regions. Therefore, the evolution of these phases is a major issue in the homogenization process of these alloys. There is a lack of information on the...

Strain-dependent constitutive analysis of three wrought Mg–Al–Zn alloys

Slooff, F.A. (author), Zhou, J. (author), Duszczyk, J. (author), Katgerman, L. (author)

The commonly used hyperbolic sine constitutive equation for metal forming at elevated temperatures, with no strain incorporated, is in principle applicable only to deformation in the steady state. However, the actual deformation processes applied to magnesium alloys are mostly in the non-steady state. In the present research, the results of hot...
