Relating to coatings,if one of two dissimilar metals in contact is to be coated,the more noble or more corrosion resistant metal should be coated.Why?
为啥更耐腐蚀的一方要被涂涂料?

防腐Relating to coatings,if one of two dissimilar metals in contact is to be coated,the more noble or more corrosion resistant metal should be coated.Why?为啥更耐腐蚀的一方要被涂涂料?
不纯的金属跟电解质溶液接触时,会发生原电池反应,比较活泼的金属失去电子而被氧化,这种腐蚀叫做电化学腐蚀.钢铁在潮湿的空气中所发生的腐蚀是电化学腐蚀最突出的例子.电化学腐蚀就是铁和氧形成两个电极,组成腐蚀原电池.因为铁的电极电位总比氧的电极电位低,所以铁是阳极,遭到腐蚀；
在更耐腐蚀的一方被涂涂料,就是阻止原电池反应的发生!

这段话的意思大致是说：关于涂层，如果一对接触的不同金属，不活泼金属被活泼金属包覆、涂覆。
这样做是利用电化学腐蚀原理保护制品，防止、延缓腐蚀。如钢铁件镀锌，铁更贵、更不活泼，被更活泼的锌涂覆，一旦发生腐蚀，锌镀层先参与反应保护钢铁制品不生锈。...
