A discussion on the measurement of grinding media

Iwasaki et al. proposed a corrosion model for the grinding media, involving two types of galvanic cells, as shown in fig. 3.in the differential abrasion cell, the abraded surface acts as an anode, whereas the un-abraded surface acts as a cathode, and the corresponding corrosion reactions are iron oxidation in the first area and oxygen reduction in the second.
