Translation guide
The process of metal or materials being gradually destroyed by chemical reactions, often with moisture or chemicals. In Japanese, the most common and general term is 腐食 (ふしょく). For rusting of iron specifically, use 錆び (さび) or the verb 錆びる (さびる). In technical contexts, 腐食 is standard, while 浸食 (しんしょく) can refer to erosion by water or wind. Be careful not to confuse with similar-sounding words.
The gradual destruction of metal or other materials due to chemical reactions, often with moisture, acids, or environmental exposure.
The gradual destruction or weakening of something non-physical, like trust, values, or institutions.
腐食 (ふしょく) is the general term for corrosion of any material by chemical reaction. 錆 (さび) specifically means rust on iron or steel. Use 腐食 for technical discussions or non-iron metals, and 錆 for everyday rust on iron objects.
腐敗 (ふはい) means 'decay' or 'rot' of organic matter, not corrosion of metal. Using 腐敗 for metal corrosion would be incorrect.
