What are the reasons for the rusting of Zhongshan medals
For medals, if they rust, it will affect the effect. What are the reasons for the rust on the medals?
The reason why iron products rust is due to the chemical reaction between iron and oxygen and water in the air, which generates a new substance mainly composed of iron oxide and ferrous oxide; And zinc alloy products do not experience this situation. The reason why zinc alloys do not rust is similar to the reason why they actively protect themselves. Due to the combination of zinc element and oxygen in the air, a fine passivation film is formed on the surface to prevent air from continuously corroding the interior of the metal matrix, and then achieve maintenance. Over time, the zinc alloy surface will be seen to change color, But after hanging off the surface, the inside is still no different from the original zinc alloy. No matter how the surface corrodes, it will not turn into something similar to rust. Many zinc alloy products nowadays have a layer of metal plated on their surface, for example, many of our keychain manufacturer Beside's products such as keychains, tags, and dog tags are nickel plated.
