用极譜仅来測定腐蝕中的某些現象,是一个很好的方法。現在为了說明极譜与腐蝕間的关系,所以先扼要談談什么叫做腐蝕,然后再介紹一些极譜法在腐蝕中的应用。一、什么叫做腐蝕金属表面受週圍介質的化学作用及电化学作用而被破坏的現象,称为金属的腐蝕。1.化学腐蝕:化学腐蝕的特征是腐蝕产物直接生成于发生反应的表面区域。高溫、干燥气体及非电介質中的
It is a good idea to use polarography only to determine some of the phenomena of corrosion. Now to illustrate the relationship between polarography and erosion, so briefly talk about what is corrosion, and then introduce some of the polarography in the application of corrosion. First, what is called corrosive metal surface by the surrounding chemical and electrochemical role of the phenomenon was destroyed, known as metal corrosion. 1. Chemical Corrosion: Chemical corrosion is characterized by the formation of corrosion products directly in the reaction of the surface area. High temperature, dry gas and non-dielectric
