Liquidmetal alloy has high resistance to corrosion for a number of reasons. Firstly, crystal defects, such as grain boundaries and dislocations, can act like galvanic cells to initiate localized corrosion – Liquidmetal does not have any such defects. Secondly, the elements we use in Liquidmetal form mechanically stable oxides which act as a passivating layer. Thirdly, the passivating layers form uniformly on the Liquidmetal surface, and so passivating elements are more effective than similar elements in a crystalline alloy.
Over the years, Liquidmetal Technologies have done various corrosion studies on our materials, and we are taking the chance to summarize some of the results here.
