Ultrasonic-based surface patterning and interfacial reaction of ZrO2 ceramics

H. J. Dong et al.

Summary: Selective surface metallization of ZrO2 ceramics was achieved using ultrasound technology, allowing for rapid and reliable connections with other metals and ceramic materials. The Sn-2Ti alloy effectively wet and spread on the ZrO2 substrate under ultrasound, creating continuous interphase layers. The bonding strength of the ZrO2/Sn-2Ti interface was well established with a shear strength of 37.1 MPa, and prolonged sonication resulted in thickening of the interfacial reaction layer and the formation of Ti11.31Sn3O10 nanocrystals.

Dependence of wetting on cavitation during the spreading of a filler droplet on the ultrasonically agitated Al substrate

Zhengwei Li et al.

Summary: The cavitation characteristics during the spreading of a pure Sn liquid droplet subjected to ultrasonication were studied. Ultrasonic vibration realized the spreading of Sn droplet on the nonwetting pure Al substrate, but the oxide layer at the spreading front is difficult to remove. The high-speed photography result showed the presence of a noncavitation region consistently at the spreading front, and the width of the noncavitation region increased with the size of the spreading area. The bubble density decreased during spreading due to the decreased acoustic pressure.

Three orthogonally arranged ultrasounds modulate solidification microstructures and mechanical properties for AZ91 magnesium alloy

Y. J. Hu et al.

Summary: This study introduces three dimensional (3D) power ultrasound sources into the solidification process of AZ91 magnesium alloy and finds that the transient cavitation intensity dominates the grain refinement and enhances the mechanical properties of the material.

Characterization of Sn-Sb-Ti Solder Alloy and the Study of Its Use for the Ultrasonic Soldering Process of SiC Ceramics with a Cu-SiC Metal-Ceramic Composite

Roman Kolenak et al.

Summary: This research characterized Sn-Sb-Ti soldering alloys and studied ultrasonic soldering of SiC ceramics with Cu-SiC metal-ceramic composites. The Sn5Sb3Ti solder demonstrated a high melting point and narrow melting interval, resulting in strong solder joints with SiC ceramics. The incorporation of antimony in the solders improves their strength, making them a cost-effective alternative to S-Bond active solder with a wider application temperature range.

High-strength vacuum diffusion bonding of Cu-plated, sandblasted W and CuCrZr alloy

Yuanyuan Chen et al.

Summary: W/CuCrZr alloy composite panels are promising plasma-facing components for future nuclear-fusion reactors, and a vacuum diffusion bonding method involving sandblasting of the W substrate surface and Cu electroplating was developed to achieve high bond strength. The improved joint obtained with this method showed superior shear bond strength and bonding quality compared to conventional vacuum diffusion bonding methods.
