Pop-up type Ocean Bottom Seismometer
electrical corrosion
titanium
600 alloy
Aiming to long time pop-up type ocean-bottom observation, we developed a weight releaser by electric corrosion of metal. During the corrosion test of a titanium and an inconnel alloy 600, we investigated their electro-chemical property and determined the specifications of batteries for it. Over 3V, the electric corrosion of inconel began with several milli Ampere, whereas the voltage of titanium electric corrosion was over 12 V, and stable chemical proccess over 20 V. Considering leaking current in use of the inconel, we determined to use titanium for the releasing system.
