在谈论铜和铜合金的耐蚀性时,首先必须注意,所谓耐蚀性并不是金属和合金的属性,而是金属和合金及其使用环境相互作用结果所决定的特性。铜以暴露使用在大气环境的情况为多,而大气腐蚀也是在金属表面存在着薄水膜时进行的。所以,在考虑金属的腐蚀问题时,首先必须以我们的生活环境为基础,了解所谓“含氧水”环境对于金 When talking about the corrosion resistance of copper and copper alloys, it must first be noted that the so-called corrosion resistance is not a property of metals and alloys, but rather a property of metals and alloys and their interaction with the environment. Copper is exposed to more atmospheric conditions and atmospheric corrosion is also caused by the presence of a thin film of water on the metal surface. Therefore, in considering the corrosion of metal, we must first of all be based on our living environment to understand the so-called “oxygenated water” environment for gold
