                         its applications. It was evaluated the influence of surface 
                         modification in NiTi SMA by nitrogen plasma immersion ion 
                         implantation (varying temperatures, and exposure time as follows:

                         increased as the implantation temperature increased resulting in 
                         the decrease of nickel release. The sample implanted in high 
                         implantation temperature presented 35% of nickel release reduction
