Abstract—The resistance to atmospheric corrosion of 25Kh1MF steel after aluminizing and thermal improvement has been studied. It is established that the low resistance of the aluminized layer to atmospheric corrosion is caused by surface defects, such as cracks and the pores, or by the partial removal of the layer containing the Fe3Al intermetallic. In the aluminized layer containing ferrite doped with aluminum, aluminum nitrides that prevent the cold diffusion welding of mating thread surfaces of fasteners are found.
