【Abstract】 As a new method to improve the quality of arc spraying, arc ultrasonic is introduced into the field of spraying. As the heat resource of arc spraying, the arc of spraying can emit ultrasonic excited by high frequency modulation. The effects of ultrasonic, such as cavitation effect, mechanical effect and heat effect, improve the atomization result of spraying materials. The application of Arc ultrasonic reduces the spraying graininess, accelerates the grain, reduces the porosity and improve the quality of spraying.更多还原
