Article Synopsis
  • Traditional electroplating of zinc in an aqueous solution leads to significant corrosion of NdFeB magnets due to hydrogen evolution reactions during the process.
  • This study explores a chloride-free nonaqueous electroplating method using zinc acetate, sodium acetate, and ethylene glycol, which demonstrates better corrosion resistance for NdFeB during zinc deposition.
  • Experimental results indicate that the nonaqueous method results in a dense, protective zinc film on NdFeB, showing superior performance and reduced damage compared to traditional aqueous electroplating methods.

This report explored a novel amphiphilic organothiol and prepared self-assembled monolayers (SAMs) on Ni substance in the aqueous micellar solution of this amphiphilic organothiol. The as-prepared amphiphilic organothiol can self-emulsify and disperse in an aqueous solution to form a stable emulsion without any additional emulsifier. The experiment shows that the self-emulsifying solution remains stable after six months at room temperature.

Benzotriazole (BTAH) and 2-mercaptobenzothiazole (MBT) are mixed to passivate electroplated copper coatings. The growth process of passive films is comprehensively analyzed from the surface potential, microstructure and chemical composition by potential-time curve, FESEM and XPS. Meanwhile, the corrosion resistance of copper coatings with different passivation treatments is evaluated by potentiodynamic polarization curves and electrochemical impedance spectroscopy.
