Surface modification of Ti-6Al-4V alloy by salt cyaniding and nitriding

A cyaniding process, operating in a molten cyanide salt, and a nitriding process, operating in a Tufftride salt bath, were applied to modify the near-surface microstructure of Ti-6Al-4V alloy. The surface-hardened layers have been characterized with respect to their hardness and microstructure. The...

Zusammenfassung:A cyaniding process, operating in a molten cyanide salt, and a nitriding process, operating in a Tufftride salt bath, were applied to modify the near-surface microstructure of Ti-6Al-4V alloy. The surface-hardened layers have been characterized with respect to their hardness and microstructure. The corrosion and wear performance can both be improved by cyaniding and nitriding.
