“…However, at a voltage of 300 V, this increase was not observed, possibly due to the formation of a thick surface layer of hydroxyapatite that prevents the identification of the underlying phases. During the PEO process, there is a local heating of the sample surface, which possibly contributes to the increase in the β-phase of titanium, which may influence the mechanical properties of the coating [23,43,44]. In addition, when the voltage is increased, the sample is heated, and anatase is transformed into a more stable form-rutile.…”

In this article, the process of creating calcium phosphate coatings through plasma electrolytic oxidation was investigated. Calcium phosphate coatings were deposited onto titanium substrates fabricated via the selective laser melting (SLM) method. The correlation between the characteristics of the coating and the applied voltage (200, 250, and 300 V) of PEO was studied. The surface morphology analysis indicates that an increase in applied voltage results in a larger pore size. It was discovered that, when a voltage of 300 V was applied, a layer of hydroxyapatite formed. However, at 300 V, the coating cracked, producing a significantly rough surface. Our analysis of the elemental composition of sample cross sections indicates the presence of TiO2 layers that are enriched with calcium (Ca) and phosphorus (P). The coefficient of friction and wear rate are primarily influenced by the morphology, pore size, and density of the titanium dioxide layer. Furthermore, a rise in the quantity of the beta phase of the titanium on the surface can be noticed as the applied voltage increases. As a result, it also affects the mechanical and tribological characteristics of the coating. The sample treated to a voltage of 250 V demonstrates a higher resistance to wear and a lower elastic modulus in comparison to the other two coatings.

“…The results show that the vibration amplitude and holding force of the tool end have the greatest influence on the cutting performance of the ultrasonic knife, while the resonant frequency has little effect on the cutting and hemostatic performance of the ultrasonic knife. He [12] studied the effect of ultrasonic scalpel and the load characteristics of different tissues from three aspects : working frequency, input admittance and reflection factor.…”

In order to take into account the high amplification factor of the stepped ultrasonic scalpel horn and the high fatigue strength at the abrupt section of the curve transition horn, an ultrasonic scalpel acoustic composite horn with the most fast curve transition section was proposed, and a series of experiments were carried out on the ultrasonic scalpel acoustic system. Firstly, the equivalent T-type circuit of the ultrasonic scalpel energy transducer was constructed based on the equivalent circuit method. The mathematical model of the transition curve structure was established. On this basis, the structure of energy transducer was designed, and the overall structure and initial size of the ultrasonic transducer was obtained. Secondly, using ANSYS to analyze the modal analysis, harmonic response analysis, transient dynamic analysis and feasibility analysis of the most fast curve of the energy transducer. The simulation results verify the rationality of the theoretical calculation. Finally, the performance of the energy transducer was tested and analyzed by experiments, and the effectiveness of the designed transducer is verified. The results show that the ultrasonic scalpel acoustic system meets the design requirements.

The utilization of Ti–Mo alloys in biomedical applications has gained attention for use in biomedical applications owing to their non-toxicity, reasonable cost, and favorable properties. In the present study, Ti–12Mo–6Zr and Ti–15Mo–6Zr alloys were prepared using elemental blend and mechanical alloying techniques. The effect of alloying elements Mo and Zr of Ti–Mo alloy, as well as the effect of fabrication techniques of Ti–Mo–Zr trinary alloys, were investigated. Thermodynamic calculations supported by CALPHAD analysis revealed that the addition of Zr increases lattice distortion, which contributes to enhancing the strength. Conversely, adding Mo decreases the enthalpy, facilitating improved mixing and solid solution formation. The as-sintered samples were characterized by X-ray diffraction, optical microscope, and scanning electron microscopy, and their microhardness, compressive, and corrosion behavior were investigated. Among all the investigated alloys, Ti–15Mo–6Zr alloy prepared by the mechanical alloying technique, milled for six hours at 300 rpm, compacted at 600 MPa, and sintered at 1250 ℃, shows good comprehensive mechanical properties with a preferable compressive strength (− 1710 MPa) and hardness (396 HV5), as well as the lowest wear rate (0.69%) and corrosion rate (0.557 × 10–3 mm/year). This can be related to the solid solution strengthening and relative density, together with dispersion and precipitation strengthening of the α phase. Remarkably, the combination of high mechanical and corrosion properties can be achieved by tailoring the content of the α phase, controlling the density, and providing new fabricating techniques for β Ti alloys.
