AbstractIn this paper, dry sliding wear and corrosion behavior of Cu + 13wt% Al +3.8 wt% Ni was prepared by powder metallurgy. Dry sliding wear has beenstudied based on pin on disk at constant velocity and constant sliding distance.Corrosion behavior in 5 wt% NaOH solution based up on potentiostatic ( Tafel )has been presented for base shape memory alloy ( Cu + 13% Al + 3.8 % Ni ) intwo cases austenitic and martensitic phase state . Further more , the effect of Fe additions as ( 0.4 , 0.8 and 1.2 wt% ) on the sliding wear and corrosion behavior of base alloy has also been studied .It is clear that Cu Al Ni shape memory alloy inmartensitic state has more wear resistance than in austenitic structure . Also ,corrosion resistances are better than in martensitic structure because the alloy hascorrosion current density as 336.45 ?A/cm2 in martansitic where as the corrosion current density is 633.62 ?A/cm2 in austenitic structure . Further more , when the iron content increases , wear and corrosion rate increase too .Keywords : Shape memory alloys, Powder metallurgy, Cu Al Ni, Dry sliding
