Why Is Zinc Good Anti-Corrosive?
What is Zinc anyway? A chemical element that we can see in the element table? In my knowledge, it is important to our body because it helps multiply our cells and that it’s helpful if you like to gain beautiful skin scientifically explained that it should not be taken too much. In the other hand, Zinc is another type of metal and the fact that pure metals do not damage other types of metal unless its contents is not strong enough to destroy the other one and that is where zinc comes in.
It is anti-corrosive because of its light contents. It is said to be helpful to our body regeneration, so if it is safe to a human body then it could be very helpful to the steel being coated in. Intensified to grab the idea of Zinc being very important in our body then it should be noted that it is also an advantage for those who need it for steels and even paints.
Metals except for Gold, palladium and platinum are known to corrode, certain processes are done to avoid corrosion, and these are enamel application, plating and painting. Galvanization is the process of adding a thin layer of zinc to a ferrous (iron) item. Zinc is mixed in paint and is used for coating iron or steel avoiding instant galvanic corrosion or rusting. Zinc is used as a sacrificial anode that isolates the iron from environment exposure, thus slowing the rusting process.
What makes zinc a good sacrificial anode is that it attracts oxidation. The reason why Zinc is used traditionally is mainly because, it has low cost and it adheres well to iron and because of these facts given then maybe now we can say it is a good anti-corrosive especially for steels and paints.
