Abstract: This research is represent the study of the influence of ultrasonic surface treatment for 50%Ni and 50%Ti alloy. The Sample was prepared by using powder metallurgy techniques; two different nanoparticles (SiC-BN) were employed. The study use of several tests were conducted such as X-ray diffraction,Vickers hardness corrosion resistant, wear behavior and Ni- Ion release obtained results showed a great improvement in hardness and wear resistant in addition significant reduction in current density and ion release.
