发明名称 Sacrificial anode in a kerf for corrosion protection during slider fabrication
摘要 A slider fabrication assembly and method for making the same are provided. A slider is formed on a substrate. A corrodible component of the slider is exposed to an environment in contact with the slider. A kerf region of the substrate is positioned adjacent to the slider. The kerf region is removable from the slider. A sacrificial anode is embedded in the kerf region and exposed to the environment. The sacrificial anode is electrically coupled to the corrodible component of the slider thereby forming an electrochemical cell. The sacrificial anode is less noble, i.e., more corrodible, than the corrodible slider component, and thus corrodes first. When the kerf region is removed, the corroded sacrificial anode is removed as well.
