“…Recent elucidations on the inhibitor efficiency of various cerium salts, including inorganic ones such as CeCl 3 [69][70][71][72][73][74], Ce(NO 3 ) 3 [74][75][76][77][78][79][80], Ce(SO 3 )₂ [81], Ce₂(MoO 4 ) 3 [82], as well as some organic Ce-salts like (CH 3 COO) 3 Ce [83,84], (HOC₂H 5 COO) 3 Ce [85], and other Ce-carboxylates [86], have been reported. Furthermore, the substantial potential of Ce-compounds as corrosion inhibitors is highlighted in various review papers [87][88][89][90][91][92][93].…”

Cerium oxide materials exhibit remarkable properties, positioning them as highly effective, environmentally friendly solutions across diverse applications. This chapter provides a comprehensive overview of fundamental concepts and technological methodologies related to cerium oxide (CeO2) and doped ceria-based materials. Emphasis is placed on electrochemical deposition, spray pyrolysis, and the sol-gel approach for synthesizing thin and thick layers of ceria. The versatility of these materials is explored, spanning from corrosion protection layers and specialized ceramic elements for sensor applications to components for solid oxide fuel cells (SOFCs) and electrodes for water-splitting cells. Additionally, the chapter delves into the promising applications of recently developed ceria-based nanomaterials in various fields, marking some advanced methods for CeO2-based materials synthesis. The key findings are succinctly summarized in the concluding section.

“…Scanning electron microscopy (SEM) images revealed rough surfaces of as-synthesized bonded magnets with dense gaps of width up to a few µm. Yang et al [ 13 ] mixed an epoxy resin lacquer with an electrostatic dilutant, sprayed it onto the as-synthesized magnets, and thus covered the gaps on the magnet surface. However, the cured resin with a thickness of about 10 µm contained numerous pores and holes.…”

“…Even so, the corrosion properties were barely adequate, as visible corrosion appeared after 216 h of the NSS test. The authors [ 14 ] proposed a corrosion model different from that in [ 13 ]. Specifically, they attributed the appearance of visible corrosion products on the surface of the adhesive coating to slow penetration of the corrosive species through the pores, thus triggering corrosion of the magnetic material at the interface between the NdFeB and the polymer resin.…”

Bonded permanent NdFeB magnets are useful in numerous applications, including electric vehicles, and the demand is steadily increasing. A major drawback is corrosion due to inadequate wetting of the magnetic particles by liquid polymers such as polyphenylene sulfide or polyamide. Recently reported methods for corrosion inhibition are summarized, and their applicability is critically evaluated. The phosphorylation of magnetic particles inhibits corrosion but does not enable appropriate properties in harsh environments. The same applies to metallic coatings, which usually contain aluminum and zinc. Advanced epoxy adhesives are a promising solution, although some authors have reported inadequate corrosion resistance. The application of composite coatings seems like an appropriate solution, but the exact mechanisms are yet to be studied.
