“…After treatment, the surface hardness increased by about 36% without significant increase of the surface roughness. In the previous investigations using the longitudinal transducers [14,20], the hardness increased by about 32% and 44%, respectively. Thus, this novel method has the same effect as a longitudinal transducer and shows potential to improve the efficiency of ultrasonic cavitation peening.…”

In industrial applications, the shafting components with high stress are easily damaged due to cyclic loads if there is no surface treatment. With the use of ultrasonic cavitation peening, the residual compressive stress and the surface hardness of these components can be improved. While traditional longitudinal vibration transducers are used to treat cylindrical workpieces, the treated areas are limited, and the treatment period is relatively long. To solve these problems, we designed a novel configuration of the piezoelectric transducer as a type of the combination of rod and ring. During ultrasonic cavitation peening, we placed the cylindrical workpieces in the ring tool to improve the limitation. However, the treated surface properties were largely influenced by the input parameters (driving voltage and rod diameters). In this investigation, the cylindrical workpieces, which were covered with aluminum foils, were first treated by ultrasonic cavitation peening to detect the intensity and distribution of the cavitation bubbles on the treated surface. Then, the sonochemiluminescence method was utilized as an additional way to find the optimal operation parameters (190 V and 16 mm). Finally, the ultrasonic cavitation process was conducted with the optimal parameters. The treatment results showed that the surface hardness increased by about 36% without significant increase of the surface roughness.

“…Since the sonotrode is cylindrical, the available area of the SCL photo is a circular region. The cavitation processing time for the cylindrical working pieces was 240 s. For the measurements of the surface properties, we used a hardness tester as per reference [20]. The material of the rod samples was made of Al alloy.…”

“…Compared to the traditional ultrasonic cavitation peening [18], the volume loss, hardness and roughness keep similar after treatment under the same investigation conditions. Therefore, this novel peening process not only takes the advantages of water jet assist but also has the similar treatment effects as the traditional ultrasonic cavitation peening process.…”

“…Although there is no residual stress measurement, the plastic deformation and the increase of surface hardness indicate that the effectiveness of this novel peening process can still be evaluated. Compared to the traditional ultrasonic cavitation peening [18], the volume loss, hardness and roughness keep similar after treatment under the same investigation conditions. Therefore, this novel peening process not only takes the advantages of water jet assist but also has the similar treatment effects as the traditional ultrasonic cavitation peening process.…”

“…Bai et al [16,17] found that when the standoff distance is smaller than 1 mm, the influence of cavitation bubbles on transducer is less than that at other standoff distances and there is an optimal standoff distance corresponding to the input power. The improvements of the surface hardness of stainless steel and aluminium alloy by ultrasonic cavitation peening were investigated as well [18]. They utilized the surface plastic deformation method to estimate the optimal process time.…”

A Novel Ultrasonic Cavitation Peening Approach Assisted by Water Jet

Ultrasonic cavitation peening is an environmentally friendly technology to improve surface properties. In the traditional ultrasonic cavitation peening process, specimens have to be immersed in a liquid and temperature control is required, which limits the wide usage of this technology due to the geometry and complicated setup. In order to improve this process, water is slowly jetted (75 mL/min) into the gap between the sonotrode tip and specimen surface. The water jet makes the gap full of water. Thus, cavitation bubbles can be generated in the gap as the traditional ultrasonic cavitation peening process. In this case, the water container and temperature control are no longer necessary. The goal of this contribution is to evaluate the treatment effectiveness of this novel approach by the impact loads, the volume loss, the surface roughness, the microhardness and the microstructure of the specimen surface. The results indicate that a higher input power is beneficial and there would be an optimal gap width for this novel ultrasonic cavitation peening process.
