APPLICATION OF THE PROTECTIVE WAYS ON THE ELECTRO CHEMICAL CORROSION RESISTANCE FOR HIGH CARBON STEEL CK80

Abstract

The effect of some protection methods on electrical corrosion resistance of high carbon steel(DIN CK 80) is studied. Electrical coating using chrome and Tin elements were implemented on some specimens to show the effect of this element on corrosion behaviorIn addition to use inhibitors and cathodic protection for the same purpose. The potential static method used for corrosion test where electricalcurrent flow through electrical open circuit where the metal represent the cation and platinum represent the anion to determine the potential of the metal and compared it with the metal potential's in electrochemical series closing the circuit and the current flow by increasing the potential +_100 milvolt through the intersection contacts to the cathodic and anodic electrode in accordance with Tafel's method and calculation of corrosion rate.It can be deduced that all methods used contributed in reducing the corrosion rates by different percentages comparing with the base metal .
