The Grain Boundary Wetting Phenomena in the Ti-Containing High-Entropy Alloys: A Review

Metals, Год журнала: 2021, Номер 11(11), С. 1881 - 1881

Опубликована: Ноя. 22, 2021

In this review, the phenomenon of grain boundary (GB) wetting by melt is analyzed for multicomponent alloys without principal components (also called high-entropy or HEAs) containing titanium. GB can be complete partial. former case, liquid phase forms continuous layers between solid grains and completely separates them. latter case partial wetting, chain droplets in GBs, with certain non-zero contact angles. The observed HEAs produced all solidification-based technologies. leads to appearance novel tie lines Twmin Twmax HEA diagrams. so-called grain-boundary engineering permits use improve HEAs’ properties or, alternatively, its exclusion if a second are detrimental.

Improved Wear and Corrosion Resistance of Microarc Oxidation Coatings on Ti–6Al–4V Alloy with Ultrasonic Assistance for Potential Biomedical Applications

Advanced Engineering Materials, Год журнала: 2021, Номер 23(4)

Опубликована: Янв. 15, 2021

Although microarc oxidation is frequently used in producing wear‐ and corrosion‐resistant coatings on Ti alloys for biomedical applications, the formation of nonuniform microstructure still unavoidable. To overcome this drawback, work adopts ultrasonic assistance Ti–6Al–4V systematically investigates influences treatment with different durations coating microstructures resultant properties. The positive effects ultrasonic, such as cavitation effect, sound flow mechanical accelerate cooling rate electrolyte promote homogeneity solute sample surface. Therefore, ultrasonic‐assisted exhibit uniform fewer cracks therefore improve performances. For instance, compared counterpart without assistance, 15 min duration demonstrates 25.1% lower mass loss tribology test half corrosion density Hank's solution. Such results indicate that can homogenize enhance their resistance wear human body.

High entropy alloy coatings for biomedical applications: A review

Smart Materials in Manufacturing, Год журнала: 2022, Номер 1, С. 100009 - 100009

Опубликована: Сен. 28, 2022

Metallic biomaterials are widely used as short and long-term implantable devices by virtue of their outstanding mechanical properties, such high load-bearing capacity fatigue resistance. Due to inherent bioinertness, potential corrosion, some inferior surface metallic generally require coating modification improve function extend lifespan in the body. High entropy alloys (HEAs) a novel class materials that composed at least five principal elements with equiatomic or close-to-equiatomic compositions. Some unique properties HEAs for include excellent corrosion resistance, remarkable wear strength/hardness, strong diffusion The on substrates can be achieved through different techniques, including thermal spraying, laser deposition, vapor deposition. have become promising candidate biomedical applications combining tailor-made topography, biocompatibility, appropriate chemistry, element composition design. present article is thorough review research using HEAs.
