摘 要: 高能率电爆炸喷涂技术是一种新兴喷涂技术,具有潜在的广阔应用前景。本文设计了一种参数可控的高能率电爆炸粉末喷涂实验系统。通过系统强脉冲电流发生电路对线圈负载加载放电过程电流脉冲响应的测量,验证了实验系统的可行性。同时利用该系统进行了Cu粉电爆炸喷涂实验,分析了初始充电电压5 kV实验条件下,Cu粉电爆炸过程中电压、电流、电阻、功率等电学参数的变化特性,计算了喷涂过程中系统能量利用率,获得了Cu粉电爆炸喷涂典型实验的重要参数。

Abstract: As a new-type thermal spraying technology, the electrothemal explosion spraying method possesses quite potential applications. Tn this paper designed and set up a electrothemal spraying system, which the parameter of charge voltage was controllable for experimental purpose of electrothermal explosion spraying using metallic powder. The discharged current response was tested to validate the feasibility of electrothemal spraying system. Furthermore, an electrothermal explosion spraying process for Cu powders was studied experimentally. The characteristics of electric parameters, such as current, voltage, power and the metal power resistance during explosion were analyzed in detail. The energy-utilization ratio of the system during the electrermal explosion was calculated when the charging voltage is 5 kV.
