PEREC, Andrzej. Disintegration and recycling possibility of selected abrasives for water jet cutting. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.203, pp.249-256. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v84n203.62592.

This paper presented a study of abrasive disintegration in a 400 MPa Abrasive Water Jet (AWJ). Abrasive particle size and distribution play a major role in machining and cutting efficiency of abrasive water jets. Tested garnet abrasive, commonly used in the abrasive water jet treatment, and corundum. It is of scientific interest to observe the disintegration of these particles which have been interactive with uncommonly used abrasive materials. Time impact of abrasive grains on the workpiece is very short and not all the grain in the stream of being able to do the work of cutting, you should expect the possibility of recovering the abrasive treatment. Considerable importance is the increase in cutting capacity crushed grains due to reveal new cutting edges. Based on a feasibility study this paper will present some results on achieved cutting data and shows also wear of the used focusing tube - the main part responsible for the formation of the jet.
