Consider the gas carburizing of a gear of 1020 steel at 927°C (1700°F) as Problem 5.2. Only in this problem calculate the carbon content at 0.50 mm beneath the sur- face of the gear after 5 h carburizing time. Assume that the carbon content of the surface of the gear is 0.90%, and that the steel has a nominal carbon content of 0.20%. 1.28 Y 10-11 m2/s

Question
**Gas Carburizing of 1020 Steel** Consider the gas carburizing of a gear made from 1020 steel at 927°C (1700°F), as outlined in Example Problem 5.2. In this problem, calculate the carbon content at a depth of 0.50 mm beneath the surface of the gear after 5 hours of carburizing. Assume the surface carbon content of the gear is 0.90%, and that the base steel has a nominal carbon content of 0.20%. **Additional Information:** - Diffusion coefficient (\(D_{steel}\)) = \(1.28 \times 10^{-11} \, \text{m}^2/\text{s}\) This information aids in understanding the carbon penetration depth and composition change due to the carburizing process, enhancing surface hardness and fatigue resistance.
