金属材料是现代最重要的材料。但是金属及其制品会受到各种不同形式的损坏,其中最重要、最常见的损坏形式就是腐蚀。 一提到腐蚀,人们就会联想到褐红色或棕黄色的铁锈。其实,金属生锈并非唯铁独有,锌和铝生白锈,铜生黑锈和绿锈,镍生绿锈。生锈不仅使金属制品变得难看,而且意味着厚度减少、强度降低、缩短使用寿 Metal is the most important material in modern times. However, metals and their products are subject to various forms of damage. One of the most important and common forms of damage is corrosion. When it comes to corrosion, people think of maroon or brown rust. In fact, metal rust is not unique to iron, zinc and aluminum white rust, copper black rust and green rust, nickel green rust. Rusting not only makes metal products ugly, but also means reduced thickness, reduced strength and shortened service life
