A survey is carried out of how various ceramics have been used or considered as materials for prosthetic heartvalves. The ceramics include pyrolitic carbon, titanium dioxide, porous and fully dense alumina, and single crystal alumina. Particular attention is paid to the ability of some types of alumina to support a stable tissue covering which then camouflages them from further interactions with the blood.

In this study, the degradable superhydrophobic Mg/P/Z/F/H (magnesi-um/poly(-caprolactone)/zinc oxide/1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTES)/ heating process) composite materials were prepared through one-step method for enhancing the corrosion resistance of AZ91D magnesium alloys. Electrochemical measurements showed that Mg/P/Z/F/H materials significantly improved the corrosion resistance of magnesium alloys in 3.5 wt.% NaCl. The self-cleaning, adhesion and stability tests suggested that Mg/P/Z/F/H composite materials had well self-cleaning properties, good adhesion strength and stability in wet atmosphere.

Superior Level

Titanium dioxide (TiO2) has widely been applied in various fields of industry and technology. To improve the corrosion resistance of TiO2, many manufacturing processes have been researched. MAO is a new method of the TiO2 manufacturing process, of which titanium dioxide is coated on titanium substrate. According to electrochemistry researches, there is a more superior level for Pulse-MAO than traditional MAO. Parameters of on-time were significant in the Pulse-MAO process. The results show that on-time affects reactant shape, morphologies, thickness of films, and corrosion resistance. When on-time increased, the size of reactants was bigger and the shape of reactants was changed from sphere to lump. Meanwhile, the corrosion resistance and thickness of the film increased.

     Titanium dioxide nanotubes (TNTs) have been considered the promising nanostructures employed for many practical applications such as biomedical, photonic and optoelectronic devices. Coatings prepared from epoxy-nano-TiO2 nanotubes synthesized by in situ polymerization were found to exhibit excellent corrosion resistance much superior to epoxy resin in aggressive environments. The corrosion studies were carried out on steel SPCC JISG 3141 plates coated with 5 wt % and without of TiO2 nanotubes (TNTs). The synthesis of titanium dioxide nanotubes (TNTs) using hydrothermal method was investigated. The synthesized TNTs were characterized with Fourier Transform Infrared Spectroscopy (FTIR), Brunauer-Emmett-Teller (BET) specific area surface test, X-ray diffraction (XRD) and Transmission Electron Microscope (TEM) imaging. The results demonstrated a unique tubular nanostructure of TNTs shape. The mechanical performance of the nanocomposites was examined to show that the 5 wt % TNTs/epoxy coating was more impact resistance, the film hardness behavior and bending resistance than epoxy coating. The effects of TNT particles on corrosion resistance of epoxy coating were studied by salt spray test (Model SAM Y90) and compared to that of non-filler. After 144 h exposure, the corrosion resistance of epoxy resin greatly improved by using reinforcing the white pigment of TNTs. The results indicated that the coating containing TNTs shows the best protection efficiency.
