| Abstract | ||
| The effect of tempering heat treatment on corrosion resistance of carbon steel DIN CK45 is investigated. Test specimens (1.5*1.5*0.3) Cm were prepared according to ASTM G71-30 Tempering Heat treatments at 150, 350 ◦ C were performed by heating the specimens in electrical furnace to 850 ◦ C and cooling in water then preheated to 150, 350 ◦ C and cooled in air. Corrosion tests were investigated by electrochemical potential state cell in prepared salt water (sea water) at multi velocities (1, 2, and 3) m/min where the test specimen represents the positive electrode (anode) pole. Tafel equation was adopted to calculate the corrosion rate. The obtained results show that the heat treatment improves the corrosion resistance by increasing the combination of iron with carbon reducing by that the combination of iron with oxygen which produces rust. On the other hand the increasing of velocity of the media (sea water) contributed in decreasing the corrosion rate because of reducing the assembling of ions on cathode pole. | ||
