For injection-moulded magnets, the effects of magnetic powder type (Nd\u2013Fe\u2013B and Sm\u2013Fe\u2013N), magnetic powder particle size (100 \u00b5m and 400 \u00b5m), and polymer binder (PPS and PA12) on corrosion resistance were studied. For compression-moulded magnets with an epoxy binder, the effects of powder type and size were examined. Corrosion resistance was investigated using potentiodynamic polarisation in electrolytes of varying pH (1.8\u201312.8). The Sm\u2013Fe\u2013N magnets exhibited slightly better corrosion resistance than the Nd\u2013Fe\u2013B magnets, irrespective of the polymer binder. The finer magnetic powders (100 \u00b5m) showed lower corrosion resistance due to their larger specific surface area, with a more pronounced effect in the compression-moulded magnets. The type of polymer binder had only a minor effect. The hygrothermal corrosion resistance and thermal stability were evaluated using bulk corrosion (BCT) and thermal shock tests, respectively. Surface corrosion was observed in all magnets after the BCT, with the compression-moulded magnets exhibiting a greater irreversible loss of magnetic properties. The thermal shock test caused a temporary reduction in magnetic properties, with recovery after remagnetisation, demonstrating the good thermal stability of both magnet types.<\/jats:p>","DOI":"10.3390\/polym18091123","type":"journal-article","created":{"date-parts":[[2026,5,4]],"date-time":"2026-05-04T00:15:02Z","timestamp":1777853702000},"page":"1123","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Corrosion Behaviour of Injection- and Compression-Moulded Nd\u2013Fe\u2013B and Sm\u2013Fe\u2013N Magnets with Different Polymer Binders"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7530-2706","authenticated-orcid":false,"given":"Nikolina","family":"Le\u0161i\u0107","sequence":"first","affiliation":[{"name":"Department of Physical and Organic Chemistry, Jo\u017eef Stefan Institute, Jamova cesta 39, 1000 Ljubljana, Slovenia"},{"name":"Jo\u017eef Stefan International Postgraduate School, Jamova cesta 39, 1000 Ljubljana, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nata\u0161a","family":"Kova\u010devi\u0107","sequence":"additional","affiliation":[{"name":"Kolektor Mobility d.o.o., Vojkova ulica 10, 5280 Idrija, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7633-9954","authenticated-orcid":false,"given":"Ingrid","family":"Milo\u0161ev","sequence":"additional","affiliation":[{"name":"Department of Physical and Organic Chemistry, Jo\u017eef Stefan Institute, Jamova cesta 39, 1000 Ljubljana, Slovenia"},{"name":"Jo\u017eef Stefan International Postgraduate School, Jamova cesta 39, 1000 Ljubljana, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"821","DOI":"10.1002\/adma.201002180","article-title":"Magnetic materials and devices for the 21st century: Stronger, lighter, and more energy efficient","volume":"23","author":"Gutfleisch","year":"2011","journal-title":"Adv.
