Pulsating water jet erosion effect on a brass flat solid surface

Popis výsledku v původním jazyce

The present study is focused on the disintegration effect of ultrasound-enhanced pulsating water jet (PWJ) technology on brassnCW614N. The first part of the study discusses the effect of a combination of factors based on the full factorial design ofnexperiments (DoE) 33. Traverse speed v (mm s−1), circular nozzle orifice diameter d (mm), and hydraulic power Ph (kW) arenselected as the disintegration variable factors. Mass material removal Δm (mg s−1) is evaluated based on the change in thesenvariable factors. In the next part, a verification experiment is performed with by varying the traverse speed between 0.2 andn1.4 mm s−1. The mathematical model calculated in DoE is confirmed. Moreover, the significant effect of hydraulic power Phn(kW) on the efficiency of the PWJ disintegration is demonstrated. The last part of the study discusses the surface and subsurfaceneffects on a PWJ after brass CW614A erosion. A sample disintegration with hydraulic power Ph = 13 kW and circular nozzlendiameter d = 1.321mmis observed. Optical profilometry and scanning electron microscopy are performed to visualise the surfacenerosion of a selected groove. A significant mass material removal is observed from the groove surface, and the disintegratednsurface is characterised by erosion and crater formation. A slight cold deformation with a maximum depth of 200 μm is detectednin the subsurface layer. The experiment and results present a part of an extensive research focused on describing the PWJndisintegration efficiency for metallic materials.
