The fluctuationofcurrent is larger than that of voltage in arc spray process. So the fluctuationofcurrent is of importance to the quality of coatings and the stability of arc spray process.
So the properties of coating will be worse. The reason is that the larger fluctuationofcurrent causes the larger nonuniformity in the size, temperature and distribution of spraying particles.
