Electrogalvanization

     The electrogalvanization process uses electricity to bond zinc to steel. In this process, 
workers run DC electricity through a zinc-salt solution. The electricity runs through an anode and 
then to the steel, which acts as a cathode. The anode in electrogalvanization can be either a block 
of zinc, in which case it serves also as the zinc component of the zinc-salt solution. It can also 
be a block of lead, in which case workers must constantly add zinc to the solution. In both cases, 
the force of electricity running through the anode to the steel causes zinc to dissolve and bond to 
the steel. During this process, dissolved particles of zinc run along the line of current. This 
brings them to the steel and deposits them on it. The constant DC electricity causes zinc particles 
to bond tightly to the steel, creating a very thin layer. As in hot-dip galvanization, the steel 
must be thoroughly cleaned prior to this process.
