The corrosion of steel in near-neutral humid air屬于吸氧腐蝕 (the same applies in seawater):
Negative electrode (Fe): 2Fe - 4e = 2Fe2+
Positive electrode (C): 2H2O + O2 + 4e = 4OH-
Overall reaction equation: 2Fe + O2 + 2H2O = 2Fe(OH)2
The role of attaching anti-corrosion zinc blocks is to protect by sacrificing the zinc block. Since zinc is more reactive than iron, zinc優(yōu)先失去電子 and reacts first. However, zinc blocks need to be replaced regularly. Proper installation ensures good electrical contact with the hull. When installing zinc blocks, the outer hull is usually already painted.

The use of zinc as an anti-corrosion metal has a long history. It is well-known for protecting ship hulls, boilers, and the outer walls of internal combustion engine cylinders. However, further exploration into materials and installation has only occurred in the last 20 years. During this time, technologically advanced countries like the United States have made improvements in materials and dimensions, while China has also continuously achieved results in research on zinc for impressed current anodes. The performance of anti-corrosion zinc with微量添加鎘 and aluminum has become increasingly effective, with these studies based on high-purity zinc. The principle is sound: zinc corrodes before iron, and ships in the ocean also附帶鋅塊. However, this is feasible during use for your own vehicle, but it would be more complicated for manufacturers to implement this approach.
