4. By spraying electrically charged paints.
5. By anodising the article.

I hope this will help you.

Answer 2

The main method of preventing corrosion is by covering it with some non reactive substances.

Corrosion is mainly due to the effect of Oxygen,reacting with the metals.

Here are some methods:
# Painting (paint do not react quickly)
# Oiling/Greasing (prevents contact of oxygen with metals)
# Galvanization 
# Anodisation

What is Galvanization?
The method of adding a layer of sacrificial metal like zinc, coating over the metal ,that produces its oxide and prevent the corrosion of the metals.

What is Anodisation?
Adding a layer of Aluminium oxide using electrolytic method,over the required metals.

NOTE:
#OXIDES OF METALS ARE NON  REACTIVE (ZInc oxide,aluminum oxide)
