“…Ti-Ni-Mo 3 and Ti-Ni-Mo 4 samples showed TiO oxides (planes (020), (022), and (222) of chart 1536851) and TiO 3 (planes (004) and (112) of chart 1529954). The presence of these oxides was also reported by Swain et al [43] and Odetola et al [44]. This behavior can be explained by the increase in the Ti/Ni ratio, as, according to Chan et al [45], the increase in the Ti/Ni ratio favors the increase in TiO and TiO 2 oxides.…”

This study aims to manufacture and characterize titanium and nickel alloys with different molybdenum (Ti–Ni–Mo) contents, focusing on the influence of these additions on the microstructure, mechanical properties, and corrosion resistance. The relevance of this work stems from the lack of research on this specific alloy and the absence of reports in the literature with molybdenum percentages above 2 at.%. Ti50Ni50−XMox alloys were produced by the plasma arc melting method, with six different compositions (x = 0, 0.5, 1, 2, 3, and 4 at.% Mo), and a comprehensive analysis of microstructure, chemical composition, thermal, mechanical, and electrochemical properties was carried out. The results demonstrated significant alterations in the microstructure of the Ni–Ti alloy with the addition of molybdenum presenting several phases, precipitates (TiNi, Ti2Ni), and oxides (Ti4Ni2O, TiO, and TiO3). The stability of the B2 phase increased with molybdenum content, and the monoclinic martensite (B19′) phase was identified only in the Ni–Ti sample. Introducing molybdenum into the Ni–Ti alloy generated the R-phase and shifted the phase transformation peaks to lower temperatures, as differential scanning calorimetry (DSC) indicated. Microhardness and elastic modulus decreased with increasing Mo content, ranging from 494 HV to 272 HV and 74 GPa to 63 GPa, respectively. Corrosion tests revealed increased corrosion resistance with increasing Mo content, reaching a polarization resistance of 2710 kΩ·cm2 and corrosion current of 11.3 µA. Therefore, this study points to Ti–Ni–Mo alloys as potential candidates to increase the range of Ni–Ti alloy applications, mainly in biomaterials, reinforcing its relevance and need in current alloy research.

“…As a result of the collision of these particles with the ground, they are deformed, adapting to the shape of the ground on which they fall. With the increase in the kinetic energy of the spray jet, the contact surface of the particles with the substrate is larger, and the effect of matching individual particles to the substrate is better [16]. As a result of the set process parameters, it is possible to produce coatings with the expected porosity.…”

“…Once molten, either compressed air or an inert gas breaks down and accelerates the molten metal toward the surface [3,7]. The genetic algorithm optimization method was utilized by Swain and others 2022 [16] to achieve the ideal parameter configuration for the plasma spray coating procedure. From an application point of view, an important question arises: what are the mechanical and microstructural properties of such materials-especially over a vast range of strain rates?…”

This paper presents the mechanical behavior of thermally sprayed coatings produced using an arc wire coating material. The produced coatings were cut and subjected to strength resistance tests in static and in dynamic loading. The compressive behavior for the strain rates between 0.001 1/s and 2612 1/s was examined. The strain rate sensitivity of the material was recognized in the material during dynamic loading using the SHPB technique. Microstructural observations were made, and properties such as changes in porosity and the microhardness of the coatings tested were examined. A significant reduction in coating porosity was demonstrated after static loading (90%) and dynamic loading (86%). The result of porosity reduction is the strengthening of the coatings through an increase in the microhardness of these coatings after loading in the static test (160 HV 0.3/8) and the dynamic test (278 HV 0.3/8). As a result of the tests, the coatings retain their cohesion and remain consistent. At the same time, they can absorb a significant amount of mechanical energy due to plastic deformation and porosity reduction. The presented results concern a completely new coating material created from a core wire.
