Industrial Application Of Galvanized Steel Sep 06, 2017

     Galvanized steel parts are mainly designed to protect steel parts from corrosion. The standard electrode potential of zinc is -0.76V, compared to carbon steel, iron and low alloy steel negative, the state of this formation of iron and zinc in the original battery, galvanized layer is the anode, it will itself dissolve and protect the steel matrix, even if the surface galvanized layer is not complete can play this role. Galvanized layer has both mechanical and electrochemical protection to iron-based body, so its corrosion resistance is quite good. Galvanized, which accounts for 1/3 to 1/2 of all plating, is the largest of all electroplating varieties.Galvanized Steel
     In the bath with galvanized liquid, the anode is made from the plated metal, and the cathode is connected with the anode and the cathode of the DC power supply respectively. The galvanized liquid consists of a solution containing a compound of coated metal, a conductive salt, a buffer, a ph regulator and an additive. After power, the metal ions in the zinc bath are moved to the cathode to form a coating under the action of potential difference. The anode metal forms metal ions into the galvanized liquid to keep the concentration of the metal ions coated. In some cases, such as chrome, is the use of lead, lead-antimony alloy made of insoluble anode, it only plays the role of transmitting electrons, conduction current.Galvanized Steel
    The concentration of chromium ions in the electrolyte should be maintained by adding chromium compounds to the bath periodically. When galvanizing, the quality of anode material, the composition of zinc plating solution, temperature, current density, power time, stirring strength, impurities and power waveform will affect the quality of coating, and need to be controlled at the right time.Galvanized Steel
