In this work the alloy has been prepared by powdertechnology and the effect of Mg and Zn additives has been studied on the corrosionrate, in artificial saliva. Samples (without additives) were prepared using powdermixture of 55 wt.% Ni and 45 wt.% Ti by blending in a ball mill for two hours, thencompacted at 800 Mpa, and then sintered at 950 oC for 9 hours under controlledatmosphere (argon). The same approach was made for the samples with 0.1, 0.2 and0.3 wt% of Mg and Zn additions. XRD test shows that the sintered samples areconsisting of two phase's martensite and austenite at room temperatures.From theresults; it was found Zn additives increase the corrosion rate while Mg additivesdecrease the corrosion rate.
