This study was focused on the theoretical modeling and numerical simulation about the speed and temperature field of metal drop in high-melting metal arc spraying. The influences of the metal drop speed and temperature field in high-speed flight temperature distribution cloud chart and different air pressures on grain’s flying speed were investigated. The result showed that, the highest speed of jet flow at the outlet of the spray gun reaches 600m/s; the air velocity quickly reduces to subsonic velocity after ejection within the spraying distance of 0-250mm . The air velocity continuously reduces along with the spraying distance increases. It is found that the grain’s flying speed increases along with air pressure increase with the biggest speed within 200-250m/s and the grain’s accelerated speed increases along with increase of air pressure and airflow speed when the spray gun structure is unchanged. Grain diameter has obvious influence on jet flow grain’s flying speed.
