“…Therefore, various surface treatment techniques are often used in the actual processing of titanium alloys to improve their surface properties. At present, the common titanium alloy surface treatment technology is mainly divided into two categories: mechanical surface treatment and electrochemical surface treatment, mainly including shot blasting, tumbling, laser impact strengthening and electroplating and other strengthening processes [4][5]. Although these processes can improve the surface properties of titanium alloys to varying degrees, they are still limited by the level of their underlying technology and still have their own process defects, which not only fail to simultaneously optimize surface integrity parameters such as roughness, hardness and residual stress, but also generate large energy consumption and environmental pollution.…”

In order to investigate the effects of different process parameters on the surface integrity of TC4 specimens and the effect of ultrasonic-assisted rolling strengthening on the enhancement of microstructure and mechanical properties of TC4 specimens, this paper uses TC4 titanium alloy specimens as the test object for ultrasonic-assisted rolling strengthening test. The results show that increasing the spindle speed within a certain range can improve the surface morphology of the specimen, reduce the surface roughness and average pro le height, and improve the surface hardness and residual stress. The reach also nds that USRP can re ne the surface grain of TC4 and introduce the grain re nement layer and work hardening layer with the same thickness on the surface of the specimen, and the hardness decreases gradually with the increase of depth. After USRP, the surface elastic modulus of the specimen is increased from 96.98 GPa to 112.96 GPa, and the corrosion resistance has also been greatly improved, with corrosion rate reduced by about 95%.

The results show that increasing the spindle speed within a certain range can improve the surface morphology of the specimen, reduce the surface roughness and average profile height, and improve the surface hardness and residual stress. The reach also finds that USRP can refine the surface grain of TC4 and introduce the grain refinement layer and work hardening layer with the same thickness on the surface of the specimen, and the hardness decreases gradually with the increase of depth. After USRP, the surface elastic modulus of the specimen is increased from 96.98 GPa to 112.96 GPa, and the corrosion resistance has also been greatly improved, with corrosion rate reduced by about 95%.

Design and Testing of a Novel Piezoelectric-Driven Microvibration Hammerhead

et al. 2023

View full text Add to dashboard Cite

A novel microvibration hammerhead consists of a piezoelectric actuator and a double cross-shape compliant mechanism (DCCM) is presented in this paper. The output force of the piezoelectric actuator can be detected in real time by an inside-installed pressure sensor. A theoretical model including the stiffness, first natural frequency, and stress of the DCCM and the displacement output of the piezoelectric actuator are established, and then they are further analyzed using the finite element analysis method. The effects of the beam thickness on the static and dynamic properties are deeply analyzed and compared. A prototype micro hammering system is constructed by integrating the microvibration hammerhead assembly and controlling system. Various experiments are also carried out to verify the basic performance of the micro hammering system.
