Could it be possible to modify the surface of Titanium (Ti-6Al-4V) discs using a plasma jet in order to obtain a negatively charge surface?

Could it be possible to modify the surface of Titanium (Ti-6Al-4V) discs using a plasma jet in order to obtain a negative charge surface? If yes, what gas/es should we use? Thanks a lot in advance...
