Abstract
This research devoted to studying improvement resistance for the medium carbon steel to erosion corrosion by coated with electro less nickel plating and used in this coated acid bath (Hydrogen number Ph = 4.5) at deferent temperature (70,75,80,85,90°C) to obtained deferent deposition rate of coating. The experimental work test were done using special device which was designed and manufactured according to [ASTM (G73)] with certain modifications. Tests were made on corrosion (3.5wt ℅) sodium chloride Nacl solution as sea water purged with CO2 gas as the corrosive media and 1wt ℅ silica sand was added as slurry to that media. After traditional weight losses technique was achieved, it was found that corrosion rate decrease with increase value of hardness which increase at increase temperature of coating solution. This indicate improvement corrosion resistance of metal. Heat treatment were done to coated specimens at deferent temperature (300,400,500,700,800°C). It was found that corrosion rate decrease at increase heat treatment temperature. This indicate improvement corrosion resistance but at higher ratio to that before made heat treatment. Smallest corrosion rate was obtained at temperature 800C°.
