Titanium surface roughening with ultrasonic pulsating water jet

Gabriel Stolarik et al.

Summary: Biomedical industries are exploring natural methods to process biocompatible materials for enhanced biological performances. This study investigates the use of water droplets produced through water hammer effect to create bio-inspired surfaces with high capillary elevation. Specifically, the study analyzes the surface morphologies and integrity of titanium alloy Ti6Al4V treated with an ultrasonic pulsating water jet at varying frequencies. The results suggest that this water jet treatment is a promising alternative to other techniques relying on solid particles for surface erosion, as it avoids artifacts and contamination.

Fatigue-based model for the droplet impingement erosion incubation period of metallic surfaces

Henk Slot et al.

Summary: This study investigated the liquid droplet erosion incubation period of ferrous and nonferrous engineering metals by using experimental fatigue data and developing a model to predict surface fatigue wear. The results showed that changes in selected metal properties could enhance the droplet impingement erosion incubation life.

Ultrasonic pulsed waterjet surface peening of an industrial aluminum-based metal matrix composite

M. Y. Amegadzie et al.

Summary: The study reveals that UPWJ peening has a significant impact on Al-MMC material, increasing both surface roughness and compressive stress. Traverse speed is a key parameter influencing the peening effect, with lower speeds potentially leading to material loss, while the best combination of effects is achieved at a speed of 700 mm/s.

Influence of the frequency and flow rate of a pulsating water jet on the wear damage of tantalum

Akash Nag et al.

Summary: This study investigated the hydrodynamic erosion of tantalum under periodic impingements of water clusters. The erosion depth of tantalum was observed to be influenced by various technological parameters, such as excitation frequency, supply pressure, nozzle diameter, and time exposure. The results highlighted the significant effects of water flow rate, frequency, and time exposure on the erosion depth of high-density materials like tantalum.
