Outer Space-The Ultimate in Benign Locations

摘要

Corrosion, being a reaction between a material and its environment, can be minimized by creating a benign environment rather than looking at expensive materials such as iridium. And, in theory, it is not hard to find a very benign environment—simply head upwards for 100 km or so into space. No water, no oxygen, and no chemicals are present to cause corrosion. Of course, there will be all sorts of other t repidations such as temperature and pressure extremes, fast moving space dust and rocks, and exposure to high levels of ultraviolet (UV) radiation, any of which may destroy many materials. But true chemical corrosion is unlikely to be a concern.
