“…The second factor should be the formation of oxide film. Owing to abundant grain boundaries, the USM treated alloy surface is conducive to be oxidized to form solid lubricant film with considerable thickness and uniformity [45,46]. Both factors can reduce the risk of abrasive wear and enhance the wear resistance of the Cu-0.2Be-1.0Co alloy.…”

Low-Be copper alloys exhibit high thermal and electrical conductivities but weak strength, hardness, wear and corrosion resistances, which limit their practical applications severely. To overcome these defects, we herein systematically investigate the effects of ultrasonic surface modification on the microstructures and properties of Cu-0.2Be-1.0Co alloy. It is found that the gradient microstructures characterized by pile-ups and dents, fine grains, dense dislocations and compressive residual stresses are generated in the 171 μm thickness surface layer of the Cu-0.2Be-1.0Co alloy by ultrasonic surface modification. As a result, the surface hardness obtains a 162% enhancement, the wear rate drops from 5.03 × 10 −4 to 3.46 × 10 −4 mm 3 •N −1 •m −1 , and the electrochemical corrosion current density decreases from 3.24 to 1.92 μA/cm 2 . These results indicate that the comprehensive properties of Cu-0.2Be-1.0Co alloy can be simultaneously improved by utilizing ultrasonic surface modification.

“…The current authors have reported that the strengthening mechanisms of material fatigue performance by the USRP treatment mainly included three reasons: (Ⅰ) USRP induced the residual compressive stress field at the workpiece surface, which could be helpful in inhibiting the beginning of fatigue crack and reducing the crack extension rate [ 23 , 24 ]; (Ⅱ) USRP caused grain refinement and hardness enhancement at the subsurface of the workpiece. The combined effect of the deep harden layer and grain refinement layer could effectively prevent fatigue crack propagation [ 25 , 26 ]; (Ⅲ) USRP further decreased the influence of stress concentration by reducing the surface roughness of the workpiece after the cutting process [ 27 , 28 ]. The reduction in stress concentration factor plays an essential function in increasing the fatigue properties of the workpiece.…”

The demand for titanium alloy has been increasing in various industries, including aerospace, marine, and biomedical fields, as they fulfilled the need for lightweight, high-strength, and corrosion-resistant material for modern manufacturing. However, titanium alloy has relatively low hardness, poor wear performance, and fatigue properties, which limits its popularization and application. These disadvantages could be efficiently overcome by surface strengthening technology, such as the ultrasonic surface rolling process (USRP). In this study, the true thermo-mechanical deformation behavior of Ti-6Al-4V was obtained by dynamic mechanical experiment using a Hopkinson pressure bar. Moreover, USRP was applied on the Ti-6Al-4V workpiece with different parameters of static forces to investigate the evolution in surface morphology, surface roughness, microstructure, hardness, residual stress, and fatigue performance. The strain rate and temperature during the USRP of Ti-6Al-4V under the corresponding conditions were about 3000 s−1 and 200 °C, respectively, which were derived from the numerical simulation. The correlation between the true thermo-mechanical behavior of Ti-6Al-4V alloy and the USRP parameters of the Ti-6Al-4V workpiece was established, which could provide a theoretical contribution to the optimization of the USRP parameters. After USRP, the cross-sectional hardness distribution of the workpiece was shown to initially rise, followed by a subsequent decrease, ultimately to matrix hardness. The cross-sectional residual compressive stress distribution of the workpiece showed a tendency to initially reduce, then increase, and finally decrease to zero. The fatigue performance of the workpiece was greatly enhanced after USRP due to the effect of grain refinement, work hardening, and beneficial residual compressive stress, thereby inhibiting the propagation of the fatigue crack. However, it could be noted that the excessive static force parameter of USRP could induce the decline in surface finish and compressive residual stress of the workpiece, which eliminated the beneficial effect of the USRP treatment. This indicated that the choice of the optimal USRP parameters was highly crucial. This work would be conducive to achieving high-efficiency and low-damage USRP machining, which could be used to effectively guide the development of high-end equipment manufacturing.

“…Unlike Lu et al, they demonstrated that as the test temperature increases, wear resistance properties decrease because of the appearance of an unlubricated NiO layer and severe delamination. A few articles have also studied the fretting wear behavior of this alloy deposited by LMD at both room temperature and high temperature [16], [17].…”
