“…Xue et al have found that by improving the friction and wear properties of Zr alloy, potential applications of Zr alloy in special fasteners for petroleum engineering can be explored [44,45]. Xu et al have made Zr alloy a strong candidate for orthopedic implant materials by improving its wear resistance [46]. The microhardness of alloy surface after 30 pulses is lower than that of other alloy samples, and a softer phase of β Nb is produced by HCPEB, thus resulting in weaker ability to resist external forces.…”

In this paper, the microstructure and wear resistance of Zr-17Nb alloy treated by high current pulsed electron beam were studied in detail. A phase change occurs after pulse treatments using X-Ray Diffraction (XRD) analysis, showing β (Nb) phase and α (Zr) phase transformed by a part of β (Zr, Nb) phase. Also, narrowing and shifting of β (Zr, Nb) diffraction peaks were found. Scanning Electron Microscope (SEM) and metallographic analysis results reveal that the microstructure of alloy surface before high current pulsed electron beam (HCPEB) treatment is composed of equiaxed crystals. But, after 15 and 30 pulse treatments, crater structures are significantly reduced. Besides, it was also found that the alloy surface has undergone eutectoid transformation after 30 pulse treatments, and the reaction of β (Zr, Nb) → αZr + βNb had occurred. Microhardness test results show that microhardness value presents a downward trend as the number of pulses increases, which is mainly due to the coarsening of the grains and the formation of a softer β (Nb) phase after phase transformation. The wear resistance test results show that the friction coefficient increases first, then decreases and then increases with the increase of pulse number.

“…Among the measured corrosion current values, the smallest value belongs to copper‐nickel+boron carbide sample (106 μA cm −2 ). In corrosion science, the general approach to corrosion is that low corrosion current and high corrosion potential means low corrosion rate or high corrosion resistance [14–16]. According to this approach, it is the copper‐nickel+10 % silicon carbide sample which is the most resistant to corrosion among the composites.…”

“…Therefore, corrosion current ( I corr ) which can be applied along Tafel curves to corrosion data must be calculated. I corr values can be used to calculate corrosion rates of the composites in accordance with undermentioned Equation 1 [16–18]:

true Corrosion rate (mm / year) = \frac{λ I_{c o r r} (E . W .)}{d}

In this study, composite samples were produced by reinforcing boron carbide and silicon carbide particles in different rates by weight into copper‐nickel powder mixture using powder metallurgy method. The prepared powder mixtures were cold pressed under 600 MPa pressure and pelletized. The pelletized samples were then sintered in an atmosphere‐controlled furnace. Scanning electron microscopy to determine the microstructure of the produced samples and x‐ray diffraction method analysis to determine the phases forming in the structure of the produced samples were used and microhardness was taken to determine the effect of boron carbide and silicon carbide on hardness. In addition to that, the mechanical properties the transverse rupture strength were investigated using three‐point bending tests. The corrosion tests were performed potentiodynamic polarization curves of the samples in 3.5 % sodium chloride solution. The highest hardness value was measured as 162 HV 0.05 in the sample reinforced with 10 % boron carbide. As the amount of silicon carbide increased, the corrosion resistance of the composite increased. Moreover, as the amount of boron carbide increased, the corrosion resistance of the composite decreased. Load‐contact depth values were examined, copper‐nickel+10 % silicon carbide has the highest peak depth of 48.12.

Ti alloys with lattice structures are garnering more and more attention in the field of bone repair or regeneration due to their superior structural, mechanical, and biological properties. In this study, six types of composite lattice structures with different strut radius that consist of simple cubic (structure A), body-centered cubic (structure B), and edge-centered cubic (structure C) unit cells are designed. The designed structures are firstly simulated and analysed by the finite element (FE) method. Commercially pure Ti (CP–Ti) lattice structures with optimized unit cells and strut radius are then fabricated by selective laser melting (SLM), and the dimensions, microtopography, and mechanical properties are characterised. The results show that among the six types of composite lattice structures, combined BA, CA, and CB structures exhibit smaller maximum von-Mises stress, indicating that these structures have higher strength. Based on the fitting curves of stress/specific surface area versus strut radius, the optimized strut radius of BA, CA, and CB structures is 0.28, 0.23, and 0.30 mm respectively. Their corresponding compressive yield strength and compressive modulus are 42.28, 30.11, and 176.96 MPa, and 4.13, 2.16, and 7.84 GPa, respectively. The CP-Ti with CB unit structure presents a similar strength and compressive modulus to the cortical bone, which makes it a potential candidate for subchondral bone restorations.
