In this research, has been studied the spread of chromium atoms mechanism, and mechanical and chemical and properties of the diffusion chrome coating layer in low carbon steel, which is considered one of the surface treatment techniques. Where many p
ractical experiences were carried out in the powdery saturation milieu to form a diffusion coating layer containing atomic chromium who will spread inside the painted
surface, and has studied some mechanical and chemical properties after doing diffusion chrome coating.
The tests results showed that the tensile strength and micro hardness and chemical corrosion resistance improved after the diffusion chrome coating, also increased the depth of coating layer By increasing the retention time in the oven and temperature, where this relationship is reflected with curve of the second degree. Conversely ductility decreased.
Search results confirm the possibility of using diffusion chrome coating as a promising treatment in raising the efficiency of machinery elements that prone to oxidation or chemical corrosion in different temperatures.
