Copper busbar corrosion protection mode

Copper busbar in daily life has a very wide range of applications, it is a new type of electrical equipment, but in use we should pay attention to a point, that is, it is prone to corrosion. Only when we have a detailed understanding of the types of copper bus corrosion, we can better use it.

1, spot corrosion spot corrosion mainly occurs in metal, its shape is mainly point, hole or needle. Pitting corrosion is an autocatalytic process, which is a common way of anode reaction. Once the corrosion is serious, it is likely to cause perforation.

2, galvanic corrosion galvanic corrosion is often referred to as bimetal corrosion, two metal potential sequence in the relative direction caused by the corrosion, the greater the potential difference between different metals, to the formation of copper bus corrosion will be more serious.

Three, gap corrosion gap corrosion, as the name implies is because there is a gap, this is due to the copper bus and other things between the surface gap, difference inflatable battery effect led to the acceleration of corrosion, and the gap will not be affected. The occurrence of gap corrosion has little relation with the type of alloy, even the corrosion resistant alloy will be affected by gap corrosion.

Intergranular corrosion this kind of corrosion is mainly related to improper heat treatment of pipelines. Alloying elements or intermetallic compounds are deposited and precipitated along grain boundaries. It is related to the fact that the grains are anode to form corrosion cells, thus accelerating the corrosion rate.

About the type of corrosion of copper tube bus, in the process of using copper tube bus at ordinary times, we need to do a good job of anti-corrosion work, do a good job of anti-corrosion treatment regularly, prolong the service life of the bus, to ensure that it can work better and more efficiently.
