What are the effects of anodizing and how to anodize

Nowadays cathodic protection law has become one of the main means of metal tube anticorrosion. In order to improve the ability of cathodic anticorrosion, we need to electroplate magnesium alloy sacrifice anode in the operation of cathodic protection. So do you know what the effect of cathode plating, and what measures should be taken for cathode plating? In this chapter, jiaozuo Ladbrokes Light alloy will give you a brief introduction to the above issues. I hope it will be helpful to those who use magnesium alloy sacrificial anode.

Sacrificial anode knowledge 1: The effects of anodizing

Electroplating is to cover other anti-rust metal substances on the product through electrolysis to improve the anti-corrosion function of the product. In general, in addition to zinc alloy sacrificial anodization can be done gold, red and other colors, the appearance of electroplating is electroplated metal color. Electroplating is a kind of cathode treatment, that is, the parts as a cathode, adsorption anode metal ions cover the surface to form a coating, in order to increase hardness, corrosion, wear resistance and so on.

Sacrificial anode knowledge 2: Anodizing measures

Electroplating is different from anodic oxidation (in anodic oxidation solution with high voltage direct current, oxygen and other oxidizing substances produced on the anodic surface oxidize the anode itself, resulting in a dense oxide surface). Electroplating is the effect of dc current on the plating solution to make the surface of magnesium alloy sacrificial anode electrochemical changes. The electrons obtained from the material on the cathode are reduced to form a coating on the cathode; The material on the anode loses electrons and is oxidized, while the material on the anode enters the plating bath.
