摘要: The breakdown process of niobium oxide depends on the current density, concentration and composition electrolyte time that film is maintained under galvanostatic polarisation. electrical associated with small oscillations in potential, presence sparks, anion incorporated holes surface. mechanical sudden variations potential; there are no anions to start avalanche large fractures film. Electrical processes can proceed same anodisation.
