在铝合金圆筒内表面进行了相同喷涂能量密度而不同电压与电容组合下电爆炸制备高碳钢涂层的实验。通过对高碳钢丝上的能量加载情况进行分析,并利用扫描电镜、维氏硬度仪等检测手段对涂层进行研究。结果表明:当喷涂能量密度一定时,低电压、高电容组合中用于高碳钢丝爆炸喷涂的能量较多,所制备的涂层平均厚度、表面粗糙度和平均硬度均较小;高电压、低电容组合中用于高碳钢丝爆炸喷涂的能量较少,所制备的涂层平均厚度、表面粗糙度和平均硬度均较大。
Experiments were conducted on the inner surface of the aluminum alloy cylinder to spray the high-carbon steel with the same spraying energy density and the different voltage and capacitance combination. By analyzing the energy load on the high carbon steel wire and using scanning electron microscopy, Vickers hardness testing methods to test the coating. The results show that when the spraying energy density is constant, the energy used for the explosion spraying of high carbon steel wires in low voltage and high capacitance combination is more, and the average thickness, surface roughness and average hardness of the prepared coatings are small. High voltage, Low energy combination of blasting for high carbon steel blasting less energy, the average thickness of the coating prepared, the surface roughness and the average hardness are large.
