A gear made of 1020 steel is to be gas carburized at 930.What is the carbon concentration at 0.95 mm below the surface of the gear after 8.0 hours of carburizing time?Discuss
Hydrogen gas can be purified by diffusion through a palladium sheet. If the concentrations on the two sides of a 5-mm-thick palladium sheet are 2.4 and 0.6 kg/m3, and steady-state conditions have been attained, compute the mass of hydrogen, in kgper hour, that passes through the palladium sheet at 500 C. The diffusion coefficient of […]
