| Abstract | beta-Nb2N, a transition metal nitride, has attracted significant interest due to its high hardness, high electrical conductivity, as well as its good corrosion and wear resistance. Herein, a simple novel method to prepare nanocrystalline beta-Nb2N coating on 430 stainless steel substrate by disproportionation of Nb(IV) ions in molten salt is developed and presented. Through this method, a dense, crack-free, uniform, and well-adhered nanocrystalline beta-Nb2N coating is obtained in NaCl-KCl-NaF-NbCl5-Nb melt at 850 degrees C for 5 h. Additionally, effects of temperature and duration on beta-Nb2N coating formation are also investigated. Results indicate that higher temperature and longer duration are more favorable for beta-Nb2N coating formation. Furthermore, the corrosion behavior of the coating was studied by potentiodynamic polarization in 3.5% NaCl solution. Result suggests that the beta-Nb2N coating can significantly improve the pitting corrosion resistance of 430 FSS substrate. |
