摘要：
NiCoCrAl layers used as anticorrosive layers characterized by additional corrosion stability enhancing agents that substantially improve the anticorrosive properties are provided. Corrosion stability is not only determined by the composition and the percentage of the main alloy elements of nickel, cobalt, chromium and aluminium, but also by the addition of corrosion stability enhancing agents, such yttrium, cerium, tantalum, niobium, silicon, titanium, zirconium, and hafnium.
