Over the years, it has been providing high-quality color anode treatment service, which has won the unanimous praise of the vast number of consumers. After the metal surface is anodized, it has beautiful appearance, durability, high appreciation value and so on. It is widely used in various industries. Welcome new and old customers to contact us. In the electrodeposition process of

, the process of anode and cathode is both unified and contradictory. As the cathode process is the process of obtaining products in the electrodeposition process, it is the main process, and the anode process is regarded as an auxiliary process subordinate to the cathode process. One of the functions of



anode is conduction, which is inseparable from the cathode process. Without the electric field formed by the anode and the cathode, the cathodic process would not be possible. Therefore, conduction is the primary and necessary function of the anode. This is an essential function of any anode. Another function of the

anode provides gold-plated ions. But this is not a necessary function. That is to say, the anode can also not provide the metal ions needed in the cathode process. For example, insoluble anodes.

, however, no matter what kind of anode it is, it will affect the stability of electrolyte and the quality of coating. Therefore, the cathodic process can not be ignored. —— Titanium alloy anode treatment process

of course, for the ideal anode process, that is, the metal can be successfully electrochemically dissolved into the electrolyte process, has been studied in detail in the kinetics of the electrode process. Based on these studies, it is possible to select appropriate anode materials, current density and some anode activators to dissolve the anode in the process of electrodeposition. However, even in the traditional electroplating process, it is not always possible to choose the ideal anode, and other methods have to be used to make up for it. For example, insoluble anodes are used in chromium plating, which rely entirely on the addition of chromic acid to the bath to supplement metal ions. This is because some anodic processes can not meet the needs of the cathodic process. When the cathodic process is normally carried out as a precondition, the anode can not always adapt to the cathodic process. Either the current density can not reach the normal dissolution level, or the dissolution can not provide metal ions according to the required valence state, or dissolve too fast. It greatly exceeds the need of cathodic process. Thus, when the anode process affects the normal operation of the cathode process, measures must be taken to adjust the anode process so that the whole electrodeposition process can proceed normally.

is an anode that can be dissolved and consumed in working fluid during electrodeposition. Most of the anodes used in most complex working fluids or in simple salt solutions where the anodic process can be coordinated with the cathodic process are soluble anodes. For example, all cyanide plating solutions, nickel plating, tin plating, etc., are using soluble anodes. Moreover, for the soluble anode, what metal to be plated, what metal to be used as the anode, absolutely can not be crowned. There have been instances of plating solution scrapping due to abnormal increase of metal impurities in plating solution due to incorrect anode placement.
