Nickel: An introduction - Explain that Stuff
2023年6月1日 It's fairly easy to polish, a reasonably good conductor of heat and electricity, and quite magnetic as well. In its strength and toughness, it's similar to iron (though less magnetic), though it's much more resistant to corrosion and oxidation (and, in that respect, more like copper). Crystals of nickel have a face-centered cubic (FCC) structure.

2020年5月4日 Yet little has been done by the mining industry to develop a comprehensive understanding of mine water corrosion, let alone allow effective modeling of corrosion caused by water. Rawat 1 concluded that corrosion in coal mines was attributable to high relative humidity (>90%), high temperature (~30 °C [86 °F]), and airborne dusts.
