摘要:
高速火焰电弧（HVAF-ARC）复合喷涂枪是高速火焰喷涂枪和电弧喷涂枪的结合体，利用产生的高速燃气来雾化加速电弧喷涂过程中产生的熔融粒子，提高了喷涂粒子的飞行速度，降低了粒子的氧化，可高效制备优质的涂层。文中利用自主开发的新型高速火焰电弧复合喷涂枪和普通高速电弧喷涂枪，分别在钢基体上制备了3Cr13涂层，通过对涂层的性能检测发现，复合喷涂枪所制备涂层的氧元素含量和孔隙率都比普通高速电弧喷涂枪制备的涂层低，分别降低了33%和49%，硬度提高了12%，复合喷涂枪制备涂层的性能得到较大的提高。

Abstract:
High velocity air arc fuel (HVAFARC) hybrid spray gun is an combination of high velocity air flame spray gun and arc spray gun. It uses high velocity combustion gas generated by its high velocity flame spraying part to atomize and accelerate the material molted by its arc spraying part, therefore the velocity of the arc spraying particles is increased, the oxidation of the coating splat is reduced, and the efficiency of the coating deposition efficiency through this compound spraying way is improved. High quality coating can be efficiently obtainedby this gun. Using a newly developed HVAFARC hybrid spray gun, a type of 3Cr13 coating deposited on a steel substrate was obtained in this study, and the coating was also prepared by a traditional air atomized arc spray gun as a comparision. The property test of the coatings shows that the oxide content and porosity of the coating prepared by the hybrid spray gun are lower than that of the traditional gun, and the hardness value of the former is 12% higher than that of the latter.
