Q3) A steel gear is needed to be improved by increasing the carbon content within an outer surface layer as a result of carbon diffusion into the steel surface. An external carbon-rich gaseous atmosphere at an elevated and constant temperature supplies the carbon. The initial content of carbon of the steel is 0.4 wt%. The surface carbon concentration remains at 1.5 wt%. For this treatment to be effective, a carbon content of 0.8 wt% must be achieved at a position 0.85 mm below the surface. Specify an appropriate heat treatment in terms of temperature and time for temperatures of 1000, 1050, and 1100 °C. At these conditions, the alloy is carbon in y-iron.
