, TaN, TaON coatings has shown that the tantalum oxide exhibits excellent insulating and protective properties, but this result is not stable. Tantalum, being a ductile metal, has the fewest defects and shows the most stable results. Tantalum nitride has the highest corrosion current, while oxynitride shows intermediate results. The damages of pure tantalum and oxide films on all samples have a tendency to self-healing.)
