Fabrication and anti-corrosion performance of superhydrophobic silane film on sintered NdFeB
An eco-friendly superhydrophobic protective film (DTMS/TEOS silane film) was fabricated on sintered NdFeB substrate through the utilization of electrochemically assisted deposition technology. The structure, properties, and film-forming mechanism of dodecyltrime-thoxysilane (DTMS)/tetraethoxysilane (TEOS) silane films were comprehensively analyzed using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS). Based on the test results, it can be determined that this film has a superhydrophobic property with a hydrophobicity angle of 152°. This special property can be attributed to the long alkyl chains in the DTMS molecule, the rough morphology, and the low surface energy of the DTMS/TEOS silane film. The surface of sintered NdFeB is coated with a layered three-dimensional network silane film that forms through the condensation of silanol substances. This film provides excellent corrosion resistance to the sintered NdFeB substrate, reducing its corrosion current density to 2.02×10−6 A/cm2. Moreover, the impact of film on the magnetic characteristics of sintered NdFeB was assessed and found to be minimal.
期刊介绍：
The Transactions of Nonferrous Metals Society of China (Trans. Nonferrous Met. Soc. China), founded in 1991 and sponsored by The Nonferrous Metals Society of China, is published monthly now and mainly contains reports of original research which reflect the new progresses in the field of nonferrous metals science and technology, including mineral processing, extraction metallurgy, metallic materials and heat treatments, metal working, physical metallurgy, powder metallurgy, with the emphasis on fundamental science. It is the unique preeminent publication in English for scientists, engineers, under/post-graduates on the field of nonferrous metals industry. This journal is covered by many famous abstract/index systems and databases such as SCI Expanded, Ei Compendex Plus, INSPEC, CA, METADEX, AJ and JICST.
