Particle velocities of arc spraying have a great influence on coatings quality. High velocity air arc (HVAA) spraying system is higher than conventional arc spraying on particle velocity and temperature. The liquid droplets are broken or fined and speeded up by a high velocity compressed air, which formo spraying particle jet. Particle velocities are determined from high speed images of particle streaks taken with a Kodak high velocity vision system and were evaluated using image analysis, The average particle velocity of 2.mm T8 steel of high velocity air arc spraying is about 296m/s.
