“…These characteristics render titanium and its alloys highly valuable in diverse fields such as aerospace, biomedical devices, and chemical-plant construction [1][2][3][4][5][6][7][8]. Ti-6Al-4V is a commercially prominent titanium alloy that finds widespread application in various industries [9][10][11][12]. Despite their many advantages, titanium and its alloys fall short in abrasion resistance, particularly under abrasive corrosion conditions, limiting their applicability in certain scenarios [13].…”

Ti–6Al–4V alloys are known for their suboptimal tribological properties and are often challenged by durability issues under severe wear conditions. This study was conducted to enhance the alloy’s wear resistance by forming a hardened surface layer. Utilizing directed energy deposition (DED) additive manufacturing with a diode laser, vanadium carbide particles were successfully integrated onto a Ti–6Al–4V substrate. This approach deviates from traditional surface enhancement techniques like surface hardening and cladding, as it employs DED additive manufacturing under parameters akin to those used in standard Ti–6Al–4V production. The formed vanadium carbide layer achieved a remarkable thickness of over 400 µm and a Vickers hardness surpassing 1500 HV. Pin-on-disk test results further corroborated the enhanced surface wear properties of the Ti–6Al–4V alloy following the additive-manufacturing process. These findings suggest that employing vanadium carbide additive manufacturing, under conditions similar to the conventional DED process with a diode laser, significantly improves the surface wear properties of Ti–6Al–4V in metal 3D-printing applications.

“…In recent years, biodegradability has been a hot topic due to zinc and zinc alloys' good biocompatibility and suitability (Locci et al , 2000; Thierry and Tabrizian, 2003; Ryan et al , 2006). Biodegradable implants of pure Zn or Zn alloy do not require long-term implantation and secondary surgery due to the deterioration of the human body compared to permanent medical grade metals such as titanium alloys, ferro alloys and cobalt alloys (Nochovnaya et al , 2017; Ahmed and Kumar, 2017; Gupta and Laubscher, 2017; Shearier et al , 2016). According to a recent review on biodegradable metals (Katarivas Levy et al , 2017; Chen et al , 2014), the performance of ideal biodegradable metal must meet three requirements.…”

Purpose The selective laser melting (SLM) technique, as a typical additive manufacturing process, is widely used for the fabrication of metallic biomedical components. In terms of biodegradability, zinc and its alloys represent an emerging generation of metallic materials for biomedical implants. The purpose of this paper is to obtain the Zn and Zn10Mg alloys with high mechanical properties using the SLM technology. The relationship between the processing parameters and the porosity of pure Zn and Zn10Mg alloy samples was investigated. Design/methodology/approach The samples were fabricated using SLM technology working in an inert gas closed chamber. Preliminary experiments were conducted to analyze the laser power and gas flow on evaporation, single track form and porosity. To evaluate the influence of factors on relative density, the response surface methodology was applied. Findings The satisfactory results of the proposed method were achieved, in which the relative density of the components reached up to 99.63%, and compression strength reached 214 ± 13 MPa under optimal processing conditions. Originality/value Zinc is categorized by its low melting and boiling point, which leads to the high porosity of the components. It is difficult to prepare the Zn alloy samples with high relative density using SLM technology. This work successfully achieved dense Zn and Zn10Mg samples and investigated their microstructure, mechanical properties and corrosion behavior.

Phase transformations in the alloy based on the orthorhombic titanium aluminide (Ti-24,3Al-24,8Nb-1,4V-1,0Zr-0,6Mo-0,3Si – at. %) were studied by differential thermal analysis. The alloy was quenched from the different phase regions (β+O, β+O+α2+(Vω), β+α2, β) and was subjected to continuous heating up to . It was found that the heating temperature of the O-alloy, which determines its phase state during quenching, affects the temperature ranges, intensity, and stages of the phase transformations during subsequent heating.
