Deposit Attack

Definition - What does Deposit Attack mean?

Deposit attack is a type of corrosive attack in which a non-uniform deposition of corrosive coating gets deposited on the metal surface and causes thinning of the metal surface. Deposit attack is considered to be a type of corrosion. When a non-uniform deposition of film is spread over the metal surface, non-uniform thinning or corrosion takes place.

Corrosionpedia explains Deposit Attack

In a deposit attack, a chemical reaction takes places between the metal surface and the deposited material, which proceeds in a non-uniform manner to the exposed area of the metal. There are various other types of corrosion in which uniform or non-uniform surface thinning takes place, such as:

  • Uniform or general attack-type corrosion
  • Crevice corrosion
  • Pitting
  • Inter-granular corrosion
  • Parting or selective leaching
  • Erosive corrosion
  • Stress corrosion
