Aluminide coatings were developed on low alloy AISI 4130 steel in the temperature range of 500~700 °C bypack cementation method. A Fe2Al5 phase was produced on the surface of the steel samples. The coating layershowed a single and a uniform structure. The growth kinetics of the coating layer exhibited a diffusionalgrowth. The activation energy for formation of Fe2Al5 was estimated to be 53.7 kJ mol-1. Oxidation tests werecarried out for both the aluminized and the bare steels in the temperature range of 500~700 °C. In the case ofthe coated specimens, the upper region of the aluminide layer was converted to an Al2O3 layer. The oxidationresistance tests showed that the presence of Fe2Al5 layer increased the oxidation resistance of AISI 4130 steelsvia formation of the Al2O3 layer. The coated specimen exhibited an increased oxidation resistance by about twoorders. The kinetics of the coating layer has also been discussed in terms of microstructural observationsand estimation of the corresponding parameters.
