DESCRIPTION

Corrosion تآكل Corrosion: The destruction of a material, especially metal, through chemical reactions. Example: rusting, which occurs when iron combines with oxygen and water. ا لتآكل: إن تدمير المواد، وخاصة المعادن، من خلال التفاعلات الكيميائية. مثال: الصدأ، والذي يحدث عندما يجمع الحديد مع الأكسجين والماء.
