Hot galvanizing is a process during which the parts produced after being immersed in a melt on a coating of pure zinc or iron alloy are connected to the base metal (iron) with metallurgical bonds.
Currently, this process is done in two ways: galvanized and dry.
In the galvanizer, zinc ammonia chloride mixture is sprinkled on the surface of the melt, and the parts enter the melt directly and at the same time as they are dipped in flux after the preparation steps.
In dry galvanizing, after the preparation steps, the parts are placed in zinc ammonia chloride solution, and after being soaked in the drier, they are placed in the melt.
Hot-dip galvanizing is always the attention of craftsmen due to increasing the life of parts in terms of increasing their resistance against chemical and electrochemical corrosion in most industries and especially in areas that are subject to corrosion.
Other galvanizing methods include:
Zinc plating (electrochemical method)
Mechanical spraying of sheradising zinc (a method of heating zinc powder in a drum)
Thermal spraying on zinc spray
Coating with zinc rich colors
