In this study, the microstructure, mechanical properties, corrosion behaviors, and in vitro biocompatibility of Zr-Mo alloys as a function of Mo content after solution treatment were systemically investigated to assess their potential use in biomedical application. The experimental results indicated that Zr-1Mo alloy mainly consisted of an acicular structure of α' phase, while ω phase formed in...

Silk Fibroin-Coated Mg Implants for Bone Repair Engineering In article number 2101724, Hui Fang, Chenxi Wang, and co-workers demonstrate an effective O2/N2 hybrid plasma activation technology to modify alloy, achieving a robust organic protein/inorganic metal interface. The silk fibroin-coated implants possess significantly improved adhesion, anti-corrosion biocompatibility, which expands the b...

Aluminum matrix composites (AMCs), reinforced with ceramic particulates, have significant applications in the field of aerospace, marine, automobiles, sports and recreation. Al-TiC particulate composite has better potential for high-temperature applications. The corrosion behaviour of Al 6061-TiC particulate composites prepared by stir casting route, has been explored in chloride medium using e...

In this paper, the corrosion resistance of laser-welded composite arch wire (CoAW) with Cu interlayer between NiTi shape memory alloy and stainless steel wire in artificial saliva with different concentrations of protein was studied. It was found that protein addition had a significant influence on the corrosion behavior of CoAW. Low concentration of protein caused the corrosion resistance of C...

Magnesium alloys have gained considerable interest as a material for automotive and aerospace applications due to its low density, high specific strength, and good castability. However, another considerable issue is their corrosion properties. This restricts their practical applications. In this present research, corrosion behavior of the AZ31B magnesium alloy was evaluated by conducting salt f...

Micron-size Ni-base alloy (NBA) powders were mixed with both 1.5 wt.% (hereinafter %) micron-size CeO2 (m-CeO2) and also 1.5% and 3.0% nano-size CeO2 (n- CeO2) powders. These mixtures were coated on low-carbon steel (Q235) by 2.0 kW CO2 laser cladding. The effects on the microstructures, phases and electrochemical corrosion of the coatings upon the addition of m- and n- CeO2 powders to NBA (m- ...

Abstract A compositionally complex alloy was designed, consisting of equiatomic concentrations four low-cost commodity elements (Al, Fe, Mn, and Si). The characterized using scanning electron microscopy energy-dispersive X-ray spectroscopy. corrosion the AlFeMnSi alloy, as evaluated potentiodynamic polarization tests electrochemical impedance spectroscopy in 0.6 M NaCl solution, comparable with...

Corrosion is explained as metal or alloy changes by chemical or electrochemical process or physical changes because of environmental effects. Corrosion occurs with oxidation and reduction reactions. In this study, Some general informations were given in the introduction section. And then, monomer synthesis, conducting polymers, nanocomposites, copolymers, and applications of corrosion protectio...

In the present study, hydroxyapatite-titania-graphene oxide (HA-TiO2-GO) nanostructured ternary composites were deposited on Ti-6Al-4V alloy by using electrophoretic deposition. The well-dispersed stable suspensions of hydroxyapatite particles with 20wt.% TiO2 and 0, 0.5, 1 2 wt.% GO prepared deposition was performed at an optimum voltage 20 V for 90 s. A novel linear approach fracturemechanics...

Two Niand Cu-free bulk metallic glasses (BMGs) of Zr65Pd17:5Fe10Al7:5 and Zr65Pd12:5Ag5Fe10Al7:5, with a critical casting diameter of 6mm and a compressive strength above 1500MPa, were developed. While the Zr65Pd17:5Fe10Al7:5 alloy showed little plastic strain before fracture, the Zr65Pd12:5Ag5Fe10Al7:5 alloy exhibited much larger plasticity by the relatively stable, intermittent propagation of...
