抄録

A molten magnesium bath was used to siliconize iron and steel specimens embedded in SiC powder for various periods at 973-1123K. The siliconized layer obtained was composed of Fe₃Si phase as the matrix and SiC phase as dispersed particles.<BR>Therefore, a hard composite layer, as high as 820 of Vickers hardness number, could be obtained.<BR>The thickness of the layer varied depending on the siliconizing temperature and time. Then the thickness was measured as to iron specimens siliconized with 5μm-SiC powder and then the diffusion coefficient was calculated as, <BR>D=34.22×10^-4exp[-186.30(kJ/mol)/RT] (m²/s). The thickness of the layer could also vary with SiC powder size of 2 to 40μm, the smaller in the size, the thicker in the layer. However, SiC powder of 5μm was thought to be suitable practically.
