Investigation of alumina formed by plasma electrolytic saturation
The process of alumina coating on the steel surface plasma electrolytic method is a method for increasing the corrosion resistance, in this process, electrolytic aluminum containing compounds should be able to cover the surface. The results show the size of a micron coating of cauliflower shape and distance of an average of about 6 microns. The coating on steel sample acted as a passive layer and corrosion resistance increases slightly. This is due to the low corrosion resistance because of the lack of uniformity and surface finish are not.
