AISI 1050 steel samples are borided for 2, 4 and 6 h at 850, 900 and 950 degrees C by the powder-pack boriding method using Ekabor-II boriding powder. After the powder-pack boriding, about 25.4 - 118.9 mu m thick FeB/Fe2B boride layers are obtained on the surfaces of the samples. The boride layers have a typical tooth morphology and their hardness is 1071 - 1460 HV0.1. The growth rate constants for the boriding temperatures of 850, 900 and 950 degrees C for the AISI 1050 steel are determined to be 1.522 x 10 (-12), 2.964 x 10 (-13) and 6.354 x10 (-12) m(2) sec (-1), respectively. The boron diffusion activation energy in the AISI 1050 steel is 162.93 kJ mol (-1).EnglishArticle1573-8973
