Definition - What does Dip Coating mean?
Dip coating is a procedure in which the material that needs to be protected with a corrosion resistant film is dipped into a container containing this corrosion resistant material in liquid form. The ferrous or steel material is completely dipped into the container and the excess corrosion resistant material falls back into the container.
Corrosionpedia explains Dip Coating
A dip coating is very similar to hot dip galvanizing. Hot-dip galvanizing (HDG) is the process of coating iron, steel or ferrous materials with a layer of zinc. This is done by passing the metal through molten zinc at a temperature of 860°F (460°C) to form zinc carbonate (ZnC03). Zinc carbonate is a strong material that protects steel and can prevent corrosion in many circumstances. Hot-dip galvanizing can be carried out cheaply and in large batches. Hot-dip galvanizing is also known as hot-dip coating.
