Abstract:	In this study, innovative hybrid spray technique is introduced with the goal to retain the relatively bigger diamond particles (mean size of 80 ìm without nickel layer). Hybrid and kinetic spraying experiments were performed using bronze/diamond as feedstock. Scanning electron microscopy and electron probe micro analyzer were employed to investigate the mechanical and thermal damages of diamond particles. Also, impact behaviors of diamond particles in hybrid and kinetic gas flow were simulated through finite element analysis (ABAQUS/Explicit 6.7-2). Diamond fracturing was significantly reduced as the impact energy sharply decreases due to the thermally softened bronze matrix through hybrid spraying.
