20.500.12556/DKUM-83397 Wear Behaviour of Multilayer Al-PVD-Coated Polymer Gears A comprehensive experimental investigation of the wear behaviour of coated spur polymer gears made of POM is performed in this study. Three different thicknesses of aluminium (Al) coatings were investigated and deposited by the Physical Vapour Deposition (PVD) process. The Al coating was deposited in three steps: By plasma activation, metallisation of the aluminium by the magnetron sputtering process, and plasma polymerisation. The wear of the gears was tested on an in-house developed testing rig for different torques (16, 20, and 24 Nm) and a rotational speed of 1000 rpm. The duration of the experiments was set to 13 h, when the tooth thickness and, consequently, the wear of the tooth flank were recorded. The experimental results showed that the influence of metallisation with aluminium surface coatings on the wear behaviour of the analysed polymer gear is not significantly important. The results also showed that the gears with a thicker aluminium coating showed greater wear than gears with a thinner coating or even without a coating. This is probably due to the fact that the aluminium particles that started to deviate during gear operation represented the abrasive material, which led to the faster wear of the contacting surfaces of the meshing gear flanks. polymer gears aluminium PVD coating Physical Vapour Deposition process multilayer coating wear polimerni zobniki obraba aluminijevi premazi preiskava materiala true true true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/polymers © 2022 by the authors Znanstveno delo 2022-11-15 12:22:35 2022-11-15 12:29:58 2025-03-26 09:37:21 0000-00-00 00:00:00 2022 0 0 Str. 1-16 št. 21, št. članka 4751 Letn. 14 Sept. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-09-27 2022-11-03 2022-11-05 621.833 129284355 10.3390/polym14214751 2073-4360 Wear_Behaviour_of_Multilayer_Al-P-Boncina-2022.pdf Wear_Behaviour_of_Multilayer_Al-P-Boncina-2022.pdf 1 897F59998B84009DFEA945BC74BFBC33 db6fd9964c14c0729bf90c0ca02b9f597e0ecf6cba48a0e12a73090c94a798c2 85a2160c-3cfe-11ee-af21-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=169680 https://www.mdpi.com/2073-4360/14/21/4751 0 95ebf929-64d8-11ed-91bc-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=164405 Fakulteta za strojništvo 0 0 0
