Galvanic Corrosion of the Titanic
The Titanic and her sister ship the Olympic were constructed on Queen’s Island, known as the Titanic Quarter, in Belfast Harbour. Construction of the Titanic was difficult and dangerous. During the Titanic’s construction, “246 injuries were recorded, 28 of them ‘severe,’ such as arms severed by machines or legs crushed under falling pieces of steel. The captain ordered the engines to be reversed, which sealed the Titanic’s fate. If the Titanic had sailed on ahead and then turned, in all probability she would have not hit the iceberg. Galvanic exchange is considered the real reason for the sinking of the Titanic sank. According to Robert Baboian, the retired director of Texas Instruments’ corrosion lab, the Titanic was a victim of rust. The dissimilar metals of the hull and rivets, bathed in electrically conductive seawater, might have created a circuit that slowly flecked away and weakened the rivets.
