A systematic review on restoration of obliterated numbers from Iron and Steel surfaces by Chemical Etching Process

Serial numbers are mostly encountered in surfaces of iron, steel and metallic-alloy surfaces. These alpha-numerical codes stand to provide unique identity to itself but are obliterated by criminals to conceal the identity of the materials by various methods. This has been commonly seen on criminal cases including motor vehicle theft. The deciphering or restoration of erased number from the surfaces is one of the main challenges for the criminal investigator and quite difficult to restore on tougher obliterations.
