The elevated temperature creep properties(90￣ 150℃) of spray deposrted ZA27 alloy containning 6% silicon have been investigated by means of ball hardness testing method. The experiment results showed that the material prepared by spray deposition has notable creep properties, comparing with that of the conventional ZA27 alloy . The creep activation energy of the spray deposited material is 3. 9 ￣ 5. 7 kJ/mol higher than that of the conventional cast ZA27 alloy. A creep formulation was derived as HB 2 -HB02=K·exp( -Q/(3RT) The reason for the improvements of the creep resistance is also analyzed.
