Abstract
Buried metal objects in seawater may undergo corrosion because of the corrosive ions such as chloride ions present in seawater. However, a paint coating may control the corrosion of the metal objects such as robots. Corrosion resistance of mild steel in 3.5 % sodium chloride solution before and after coating with Asian guard red paint has been evaluated by polarization study and AC impedance spectra. In presence of Asian guard red paint, the linear polarization resistance increases, corrosion current decreases, charge transfer resistance increases, double layer capacitance decreases and impedance value increases. That is corrosion resistance of mild steel objects in 3.5 % sodium chloride solution increases after coating with Asian guard red paint.
Highlights
Metallic parts of machines of ships or aero planes may submerge in sea water
The robots made of materials such as mild steel may undergo corrosion when they come in contact with sea water, while is search
If a paint coating is given, it will control the corrosion of these proposed materials
Summary
This article is divided into two part. Part A deals with “Deep learning based Underwater Metal object detection using input Image data”. Paper is available on the website: www.idk.org.rs/journal resistance of mild in3.5% sodium chloride solution is measured before coating and after coating by electrochemical studies such as such as polarization study and AC impedance spectra [1-20]. When a protective film is formed on the metal surface, the linear polarisation resistance (LPR) increases and the corrosion current (Icorr) decreases.
