Model for patterned erosion

A ball valve micropump in glass fabricated by powder blasting

“…3, we report the timedependent hole depth obtained from the experimental results represented in Fig. 2b and d. The full curve confirms the theoretical model form Slikkerveer and in't Veld [14], which only takes into account the primary impact of particles. …”

“…When the glass wafer is covered by an erosion-resistant polymer mask, containing a circular aperture, the hole eroded in the glass has a rounded shape originating from the reduced normal impact of the particles near the mask edge [14,15]. The essential role of the secondary particle impact can be illustrated by positioning the mask aperture at the edge of the substrate, as shown in Fig.…”

A level set methodology for predicting the surface evolution of inclined masked micro-channels resulting from abrasive jet micro-machining at oblique incidence

“…Analytical modeling of the surface evolution of features machined using AJM in masked glass substrates was pioneered by ten Thije Boonkkamp and Jansen [1] and Slikkerveer et al [8]. In these models, the local surface velocity was related to the local surface slope, the erosion rate of the target, and the particle velocity and flux of the arriving particles.…”
