| 英文摘要 | Nickel was incorporated into CrSiN coatings to improve their electrochemical properties. The incorporated Ni existed as elementary substance (zero valence) regardless of concentration (5.2-13.9 at %). Ni-CrSiN coatings with a thickness around 2.5 mm all presented the nano-composite structure composing of CrN crystal, amorphous nickel and amorphous SiNx. With increasing Ni content, the morphology of Ni-CrSiN coatings became compact. The electrochemical impedance spectrum results showed that the charge transfer resistance (R-ct) of Ni-CrSiN coatings increased from 1.62 x 10(6) to 3.51 x 10(6) Omega cm(2) as Ni concentration increased from 0 to 8.3 at %. Meantime, the corrosion current density (i(corr)) decreased to 18.54 nA/cm(2) owing to the extra formation of nickel oxides. In contrast, icorr increased to 31.83 nA/cm(2) at Ni concentration of 13.9 at % due to the premature pitting of passive layer. (C) 2020 Elsevier B.V. All rights reserved. |
