| 英文摘要 | Pore defect is a primary bottleneck limiting corrosion resistance of the coatings. The relationship between porosity and corrosion behaviors of HVAF-sprayed Co 21 Fe 14 Ni 8 Cr 16 Mo 16 C 15 B 10 high entropy metallic glass (HE- MG) coatings was investigated by 3D XRT, XPS, SKPFM and SVET techniques. The potential difference between pores and surrounding regions expedites corrosion tendency. The corrosion current density of the coating and concentration of defects in passivation film increase as a function of porosity, thereby degrading corrosion resistance. The lowest porosity coating displays exceptional anti-corrosion due to compact films enriched with Cr2O3 and Mo4+ oxides. These findings provide valuable insights for designing corrosion-resistance coatings. |
