ABSTRACT:
A cyaniding process, operating in a molten cyanide salt, and a nitriding process, operating in a Tufftride salt bath, can be utilized 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 be both improved by cyaniding and nitriding.
