Corrosion Resistant Behaviour of Herbal Plants on Various Metals:

Brass, mild steel and copper have been used in various industrial applications. The economic impact can be reduced by reducing material losses, as well as subsequent economic losses, e.g. the corrosion of piping, tanks, metal components of machines, ships, bridges, marine structures, etc. Corrosion of turbine blades, bridges, airplane components, automotive steering mechanisms, pressure vessels, boilers and metallic containers for toxic chemicals are a few examples of catastrophic consequences, hence safety is a critical consideration in equipment design. Though many synthetic compounds have shown good anticorrosive activity, most of them are highly toxic to both human beings and environment. The known hazardous effects of most synthetic organic inhibitors and restrictive environmental regulations have now made many researchers to focus on the need to develop cheap, non-toxic and environmentally benign natural products as corrosion inhibitors.In the present investigation, an attempt has been made to examine the dissolution of copper, Brass and mild steel in acid environment containing various green plant extract were used as corrosion inhibitors.
