Phosphate conversion of electroplated Ni coatings on NdFeB magnets improving the anticorrosion property

Improved Interfacial Interactions of Dip Coatings by In Situ Introducing Silica to Enhance Corrosion Resistance and Metal Bonding Strength

“…Corrosion is an irreversible phenomenon in nature that has been a major source of metal degradation. Improving metal corrosion resistance has long been a priority in engineering and public applications. , Cathodic protection, chemical conversion films, electroplating, and organic coatings are examples of traditional corrosion protection methods. − These methods are generally plagued by problems with multistep procedures, high electrical energy consumption, environmental pollution of the precursor reaction solutions, and high toxicity of the synthesis and operation. − As a result, such coatings cannot be used on mass-produced food packaging canisters. Coatings with characteristics such as simple operation, nontoxicity, and impressive corrosion resistance are becoming increasingly valuable in practical applications.…”

The microstructure and protective properties of electroplating zinc films on NdFeB from a chloride-free nonaqueous bath

“…[7][8][9][10][11] Presently, the primary approach to protecting NdFeB from corrosion involves utilizing various coating materials. [12][13][14] Metal coatings, such as Ni, [15][16][17][18] Ni-P, 19,20 Ni-Cu, 21,22 Zn, [23][24][25][26] are the most popular choices in the industry. So far, aqueous electroplating is still the most widely used method of metal coating deposition, [27][28][29][30] although physical vapor deposition, [31][32][33] chemical vapor deposition, 4 thermal spraying, 34 and other technologies have also developed.…”
