The fluctuation of current is larger than that of voltage in arc spray process.
实验发现亚稳态电流波动峰具有快速上升、缓慢下降的特点。
The fluctuation of current is larger than that of voltage in arc spray process. So the fluctuation of current is of importance to the quality of coatings and the stability of arc spray process.
由于喷涂过程中电压的波动范围不大,而电流的波动范围较大,因此喷涂电流的波动对电弧喷涂过程的稳定性及涂层质量的影响更为突出。
So the properties of coating will be worse. The reason is that the larger fluctuation of current causes the larger nonuniformity in the size, temperature and distribution of spraying particles.
文中从理论上对电流波动影响涂层性能的机理进行了分析,认为电流波动造成电弧喷涂雾化粒子尺寸、温度、空间分布等不均是造成涂层综合性能不高的主要原因。
