abstract = "NiTi SMA presents application in several areas such as aerospace,
robotic and it is a promising material as a biomaterial due to
their shape memory and superelastic properties. This work presents
the effects of surface modification by the use of nitrogen plasma
immersion ion implantation (PIII), varying temperatures, and
exposure time as follow: <250°C/2hours, 290°C/2hour, both by ion
bombardment heating and 560°C/1hour using sample holder heating.
The samples were taken from Ti-49.93at % Ni SMA produced by the
ITA group using vacuum induction melting (VIM) process. The wear
resistance was analyzed by pin-on-disc test and surface
characteristics (before and after the wear test) by MEV and X-ray
diffraction. The DSC measurements were carried out in order to
analyze the influence of PIII on the martensitic transformation
temperature.",
