摘要: 高速电弧喷涂技术是热喷涂技术中的高新技术,高速电弧喷涂枪是实现高速电弧喷涂的关键装置。采用高速气流技术方案研制了高速电弧喷涂枪,在喷枪的设计中采用了超音速喷管,使喷枪出口80mm范围内雾化气流的速度达到600m屉以上,这有利于增强喷涂粒子的雾化效果,提高粒子速度。高速电弧喷涂Al粒子的平均飞行速度达到了340m屉,是传统电弧喷涂的1.4倍,从而使喷涂层的质量和性能明显改善,为高速电弧喷涂技术的工业应用奠定了基础。

Abstract: High velocity arc spraying is one of the high tech processes in thermal spray devices where the high velocity arc spraying gun is the key equipment. High velocity airflow is adopted and supersonic nozzle is used in the design of a HVAb gun. The axial airflow speed of the gun is kept at approximately 600m/s at a distance of some 80mm from the gun outlet, which makes the velocity of Al particles sprayed arrive at 340m/s. The sprayed particles have a velocity 1.4 times that of the traditional arc spraying, which makes the quality and behaviors of the coating improved. The successful development of HVAS gun sets a founda?tion for its induvStnai applications.
