Study Regarding Gravimetrical Corrosion of the Superficial Layers Obtained through Electrical Discharge

Abstract

The experimental research was made on superficial layers laid-down through electrical sparking on the steel carbon OLC 45 probes, the used electrode being made from a corrosion resistant material (Copper).
The probes was immersed 285 days in static see water at the environments temperature.
The corrosion speed was determined through gravimetrical method; the superficial layers subjected to the corrosive agent were analyzed by optical metallographic and atomic force microscopy.
