The concentration of carbon on the surface of a 1018 steel gear is 0.8 wt% at 1000°C. Determine the flux of carbon atoms from the surface to a plane 25 _m below the surface where carbon concentration is unaffected by the surface concentration. Hint: convert wt% to atoms/m3 using information in Table 3.2.
