Supercorroding Galvanic Cell Alloys for Generation of Heat and Gas

摘要

This report describes supercorroding magnesium alloys that operate like galvanic cells and react rapidly and predictably with seawater to produce heat and hydrogen gas. The alloys are formed by a mechanical process that bonds magnesium and noble metal powder particles together in a strong electrical and mechanical bond. The alloy powders can be compacted and sintered to form barstock, etc., suitable for making self-destructing links. (Author)
