Mapping cavitation activity around dental ultrasonic tips [PDF]
Clinical Oral Investigations, 2012 Cavitation arising within the water around the oscillating ultrasonic scaler tip is an area that may lead to advances in enhancing biofilm removal. The aim of this study is to map the occurrence of cavitation around scaler tips under loaded conditions.Two designs of piezoelectric ultrasonic scaling probes were evaluated with a scanning laser vibrometer

Ultrasonic cavitation abrasive finishing
, 2019 The development of Powder Bed Fusion (PBF) additive manufacturing process has built a new manufacturing paradigm for metal end-use components. However, the as-manufactured components often have poor surface quality and require post-process finishing. The unique morphology of PBF surfaces poses a huge challenge to most existing processes.
