A gear component (0.2% C) is carburized with C for increased hardness. By specification, a carbon concentration of 0.75% C is required at an 80 um depth. Calculate the time required (ir hours) at 1100°C with the gas surface concentration of 1.3 % C. D=5x10-13 m2/s. Show relevant steps how you arrived at the answer Comment on whether the suggested carburizing time of 3 hours is sufficient, also mention the calculated time in hours
