20.500.12556/RUL-182213 Ice as an abrasive: Effects of particle properties and workpiece material on erosion Ice abrasive waterjet (IAWJ) machining offers a promising alternative to conventional abrasive waterjet technology because ice particles do not leave solid residues on the processed surface. However, the erosive behaviour of ice particles and the influence of their physical properties are still insufficiently understood. In this study, the erosion potential of ice particles was systematically investigated as a function of particle temperature, size, shape, and ice quality. Controlled ice blasting experiments were performed on ductile aluminium and brittle glass workpieces, using angular ice particles produced from distilled and degassed water as well as from tap water, and spherical particles produced from tap water. Three particle size fractions were tested at particle temperatures of −78.5 °C and −196 °C under perpendicular impact conditions. Particle velocities were measured using high-speed imaging combined with particle image velocimetry (PIV). Surface damage was evaluated by analysing the areas of craters generated by individual particle impacts using optical microscopy. The results show that erosion behaviour strongly depends on the interaction between particle properties and the deformation mechanism of the target material. For ductile aluminium, erosion was dominated by micro-ploughing, and the most effective particles were medium-sized angular particles produced from distilled and degassed water. Particle temperature and ice quality had a stronger influence on crater size than particle shape. In contrast, erosion of brittle glass was governed by fracture mechanisms, and the highest erosion potential was observed for the smallest spherical particles, where impact frequency plays a greater role than the energy of individual particles. ice abrasive waterjet ice blasting ice particle erosion particle impact erosion erosion mechanisms ice particle properties ledni abrazivni vodni curek ledeno peskanje erozija ledenih delcev udarna erozija delcev mehanizmi erozije lastnosti ledenih delcev true false true Angleški jezik Slovenski jezik Članek v reviji 2026-05-04 08:42:51 2026-05-04 08:43:00 2026-05-05 04:44:14 0000-00-00 00:00:00 2026 0 0 17 str. art. 206702 Vol. 595 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.924.9 1873-2577 10.1016/j.wear.2026.206702 276855555 Vinetic,_Jerman,_Valentincic......Ice_as_an_abrasive....pdf Vinetic,_Jerman,_Valentincic......Ice_as_an_abrasive....pdf 1 0544F0615B371C9EADDF29EF8139480C ce3a9c393cbb8300452ff7ec089d56d650899fb6b18ecc03f76d199e5d57158a 100ab42c-4785-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=233258 https://www.sciencedirect.com/science/article/pii/S0043164826001924 1 36f9c3d0-4784-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=233257 Fakulteta za strojništvo 0 0 0
