X-ray diffraction (XRD), scanning electron microscope (SEM), immersion, electrochemical, and tensile tests were employed to analyze the phase constitution, microstructure, corrosion behaviors, and tensile properties of a Ti-6Al-4V alloy and a newly-developed low cost titanium alloy Ti-4Al-2V-1Mo-1Fe. The results showed that both the Ti-6Al-4V and Ti-4Al-2V-1Mo-1Fe alloys were composed of α and β phases. The volume fractions of β phase for these two alloys were 7.4% and 47.3%, respectively. The mass losses after 180-day immersion tests in 3.5 wt.% NaCl solution of these alloys were negligible. The corrosion resistance of the Ti-4Al-2V-1Mo-1Fe alloy was higher than that of the Ti-6Al-4V alloy. The tensile tests showed that the Ti-4Al-2V-1Mo-1Fe alloy presented a slightly higher strength but a lower ductility compared to the Ti-6Al-4V alloy.

“…Among various light-weight metallic materials, magnesium and its alloys exhibit great potential because of their low density, high specific strength and stiffness, good machinability, and so on, which were therefore considered as the next generation of green engineering structural materials [1][2][3][4][5]. Nevertheless, the absolute strength and elasticity modulus of magnesium alloys are relatively low, which could not meet the requirements of practical applications [6][7][8][9]. As a consequence, hard ceramic particles are always incorporated with magnesium alloys to fabricate magnesium matrix composites with improved mechanical properties [10][11][12][13][14][15][16].…”

In this study, the dry sliding wear behaviors of SiC particle reinforced AZ91D matrix composites fabricated by stirring casting method were systematically investigated. The SiC particles in as-cast composites exhibited typical necklace-type distribution, which caused the weak interface bonding between SiC particles and matrix in particle-segregated zones. During dry sliding at higher applied loads, SiC particles were easy to debond from the matrix, which accelerated the wear rates of the composites. While at the lower load of 10 N, the presence of SiC particles improved the wear resistance. Moreover, the necklace-type distribution became more evident with the decrease of particle sizes and the increase of SiC volume fractions. Larger particles had better interface bonding with the matrix, which could delay the transition of wear mechanism from oxidation to delamination. Therefore, composites reinforced by larger SiC particles exhibited higher wear resistance. Similarly, owing to more weak interfaces in the composites with high content of SiC particles, more severe delamination occurred and the wear resistance of the composites was impaired.

“…It has been attracting attentions in various potential applications for lightweight equipment, electronics industries and biomedical fields [1,2]. Nevertheless, the poor corrosion resistance due to the low electrode potential and non-compact natural oxidation passive film [3,4], is still the major drawback [5,6]. Surface modification is a main strategy to protect Mg alloys from corrosion [7][8][9].…”

Magnesium (Mg) alloy has drawn considerable attention for lightweight structural and functional materials, whereas its corrosion resistance still requires to be enhanced. A new strategy for corrosion resistance has been proposed as making an amorphous-crystalline nano-composite film on Mg alloys. The film as the composition as Al 2 O 3 /GaN with a thickness of 20 nm was prepared on AZ31 Mg alloy by atomic layer deposition. Grazing incidence x-ray diffraction, scanning electron microscopy equipped with energy-dispersive spectroscopy, transmission electron microscopy, x-ray photoelectron spectroscopy, and nano indentation tester have been used to characterize the film in details. It is verified the sample has an amorphous/crystalline/Mg interface structure, and a surface with homogeneous elemental distribution and higher hardness. Neutral salt spray test shows the film changes the corroded mode from pitting corrosion to uniform corrosion. Furthermore, electrochemical measurements indicate that the film would raise E corr (ΔE corr =+0.295 V), drop i corr (about 1/10 times), and make electrical equivalent circuits change from R s (CPE R ct (R L L)) to R s (CR f ) (CPE R ct (R L L)). All evaluations show that better corrosion resistance has been by inducing the amorphouscrystalline nano film. The amorphous layer in the film would make a more homogeneous Cl − distribution in the surface and act as a barrier to block the penetration of corrosion medium in the early stage. During corrosion, the interface between the layers in the film could retard the corrosion crack propagating further. The film would be favorate to form a denser corrosion product layer finally. A more uniform and lower corrosion occurs for AZ31 Mg alloy with this nano-composite film.
