Aspen Research Announces a ground-breaking look at:
Characterization of ‘As-Received’ Nickel – Titanium Alloy Wire by Cyclic
Potentiodynamic Polarization
To be presented at MPMD
Tuesday August 11, 2009 at 9:00 am
in Salon F of the Minneapolis Hilton
Presenter is Dr.

Presentation will be posted here on August 12th
ABSTRACT
It is well understood that the surface finish of nickel-titanium alloy wire
control its resistance to corrosion during cyclic potentiodynamic polarization (CPP).
In phosphate buffered saline solutions, differences in breakdown potentials
differ by over 800 mV , . Nickel-titanium wire is commercially available in a
variety of surface finishes ranging from “Black' to ‘Bright.' This study was
carried out to determine what affect commercially available surface finishes
have on the corrosion resistance of the ‘, as-received' wire. Wire with
varying levels of oxide coatings (‘Black Oxide,' ‘Dark Oxide,' and ‘Light
Oxide') as well as “Bright” finishes available for a same source, were
chosen for investigation following the protocol described in ASTM F2129 .
Differences in the corrosion appearance and performance of the wire with respect
to the rest potential (Er), breakdown potential (Eb) and protection potential (Ep)
are reported.
