Summary: In-situ (Nb,Ti)C particles reinforced Ni0.6CoFe1.4Nb0.05 medium-entropy alloy composites were successfully fabricated by vacuum induction melting technology. The synthesis mechanism of (Nb,Ti)C and its effect on the microstructure evolution, mechanical properties, and wear behaviors were analyzed. The volume fraction of (Nb,Ti)C significantly improved the micro-hardness and tensile strength of the composites, while the friction coefficient and wear rate showed a decreasing and then increasing trend with the increase of (Nb,Ti)C content.

Summary: In this study, the morphology, microstructure, and nano-mechanical properties of Ti-Zr-Hf-Nb-Ta high entropy alloy thin films were investigated by controlling the deposition power and film thickness. It was found that the amorphous fraction of the films changed with different deposition power ranges, with an increase in crystalline phase at low power, the appearance of amorphous phase at intermediate power, and re-crystallization at high power. Thicker films exhibited higher crystallinity and increased strength with increasing deposition power.

Summary: Annealing treatment improves the microstructural stability and mechanical properties of Ti-Zr-Nb alloy, making it suitable for aerospace applications. The microstructure of the alloy undergoes recovery, recrystallization, dislocation density reduction, refinement of a0-prime martensite phases, and dissolution of u-phases with increasing annealing temperature, resulting in the release of distortion energy and improved microstructural stability. Additionally, the mechanical properties remain unaffected after annealing.

Summary: The potential of enhanced corrosion resistance of Ti(N,O) cathodic arc evaporation-coated 304L stainless steel using oxide nano-layers deposited by atomic layer deposition (ALD) was explored in this study. Al2O3, ZrO2, and HfO2 nanolayers of two different thicknesses were deposited onto Ti(N,O)-coated 304L stainless steel surfaces by ALD. The anticorrosion properties of the coated samples were investigated using XRD, EDS, SEM, surface profilometry, and voltammetry. The amorphous oxide nanolayers exhibited lower roughness after corrosion attack and the thickest oxide layers showed the best corrosion resistance. The thicker oxide nanolayers enhanced the corrosion resistance of the Ti(N,O)-coated stainless steel in a saline, acidic, and oxidising environment, which is important for corrosion-resistant housings in advanced oxidation systems.

Summary: The effect of deposition temperature on the structure, morphology, hardness, electrochemical evaluation, degradation properties and functional peptides adhesion of Mg and Si-doped hydroxyapatite coatings was investigated. The results showed that an increase in deposition temperature led to an improvement in hardness and corrosion resistance. The degradation rate of the coatings was slowed at higher deposition temperature, especially in DMEM medium. Both deposition temperatures are suitable for further bio-inspired coating with a mussel-derived peptide, to facilitate biointegration.
