摘要：
Chemical interaction in cold-sprayed Zn/Cu composite coating was investigated. Complex hybrid microstructure was formed at the boundaries of the two different particles during cold spraying, including intermetallic compounds (CuZn5 and Cu5Zn8) and amorphous-phase. It's conjectured that the driving force of the reaction mainly came from the kinetic energy released by the impact of the high velocity particles, and the accumulation of deformation energy from the serious plastic deformation of particles.
