Abstract: The velocities of atomization gas and particles are
measured．The properties of particle bunch distribution and arc are
studied．Contrast with traditional arc spraying technique, the high
velocity arc spraying technique has some unique merits, it has important
value of research and application．
Key words: High velocity arc spraying technique Particle bunch Arc
