Zinc based alloy rings with good wear resistance property were prepared by an advanced centrifugal spray forming technique in this paper. The formability and structural characteristics of these alloys under the novel processing conditions were studied. The result shows that the shape of ring preform is regular and its thickness is uniform. The structure of as deposited material is fine and homogeneous. The processing conditions have significant influence on the quality of spray deposited zinc based alloys. By means of inserting transition metal between substrate and deposit, compound rings with good metallurgical bonding interface could be produced.
