v.侵蚀
Some metals ,such as cobalt,nickel,chrome and so on ,can corrade the element in high temperature melting state and affect the service life of element. 部分金属如钴、镍、铬等在高温熔化状态可以对元件造成侵蚀，影响元件的寿命。
Nowadays the corrade of debris under water to ancient weapon is much more than that hundreds years ago. 现今水中化工残物对古器侵蚀肯定较百年前迅速多了。
In Han culture circle there seems no such weapon with complex pattern on steel,especially in early time.Moreover,how to add that pattern?Carve?Corrade? 汉文化圈里好象不会出现这种在钢铁上有复杂花纹的兵器，特别是早期。而且，那个花纹是如何弄上去的，錾刻?腐蚀?
Titanium coated CBN products are used for vitrified and some high-temperature metal bond system the coating can reduces the destruction by thermal and chemical corrade. CBN镀钛产品用于陶瓷和某些高温结合剂体系，镀层可减弱CBN晶体所受的热破坏和化学侵蚀。
