Hot Dip Coating

In  hot dip coating, the workpiece is submerged in a vat of molten metal.  When the workpiece is removed from the vat, a layer of the coating metal has bonded to it.

Process Characteristics

Is performed in a tank of molten metal
Deposits a layer of the melted source metal on the submerged workpiece
Typically utilizes source metals with a low melting point
Is a relatively inexpensive way to coat a workpiece, but coating is thick and uneven
Requires a clean workpiece surface
