Alternative approach for cavitation damage study utilizing repetitive laser pulses. Ren, F., Wang, J. J., & Wang, H. Wear, 270(1–2):115–119, 2010. ![Alternative approach for cavitation damage study utilizing repetitive laser pulses [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex Cavitation is a common phenomenon in fluid systems that can lead to dramatic degradation of solid materials surface in contact with the cavitating media. Study of cavitation damage has great significance in many engineering fields. Current techniques for cavitation damage study either require large scale equipments or tend to introduce damages from other mechanisms. In this project, we utilized the cavitation phenomenon induced by laser optical breakdown and developed a prototype apparatus for cavitation damage study. In our approach, cavitation was generated by the repetitive pressure waves induced by high-power laser pulses. As proof of principal study, stainless steel and aluminum samples were tested using the novel apparatus. Surface characterization via scanning electron microscopy revealed damages such as indentation and surface pitting, which were similar to those reported in the literature using other state-of-the-art techniques. These preliminary results demonstrated the new device was capable of generating cavitation damages and could be used as an alternative method for cavitation damage study.
