Spring passivation phenomenon can
is divided into two types: organic chemical passivation and photoelectric catalysis passivation.
Spring factory is introduced, such as iron quickly dissolve in the dilute nitric acid, but in the nitric acid melting phenomenon is basically completely annulled;
Aluminum in dilute nitric acid is not very smooth, but it can
used aluminium vessels to store the nitric acid;
Carbon steel in general is very easy to rust in the air, but by adding a steel chrome nickel base alloy composition after they became 'stainless steel'.
The passivation phenomenon called passivation of organic chemistry.
Another passivation phenomenon results from the anode electric polarization, known as the photoelectric catalysis passivation.
* most organic chemical passivation phenomena are in fact according to the electrochemical mechanism of, because the organic chemical passivation can also observe the marked shift to electric potentials.
The potential of iron in the active state is about -
0.
5 ~ -
0.
2 v, and in the condition of passivation is + 0.
5 ~ + 1 v.
Potential for - chromium in the active state
0.
6 ~ -
0.
4 v, while in the condition of passivation is + 0.
8 ~ + 1 v.
Therefore, passivation can make electric potential to the cardinal point move violently, and passivation of the precious
spring (spring potential is approximately equal to the *
Such as gold platinum)
The potential.
Despite the emergence of the passivation sex utility is common and is prominent, but until now no unified accurate expression.
Based on the theory of galvanic battery principle foundation, blunt anode process because the block caused by the spring or the high corrosion state of the aluminum alloy (
Although from thermal insights, the spring * accessories and aluminum alloy is completely can reflect)
。
Because blunt anode process management, in other words, enhance the corrosion caused by state.
