Answer:
135 hour
Explanation:
It is given that a carburizing heat treatment of 15 hour will raise the carbon concentration by 0.35 wt% at a point of 2 mm from the surface.
We have to find the time necessary to achieve the same concentration at a 6 mm position.
we know that where x is distance and t is time .As the temperature is constant so D will be also constant
So
then we have given
and we have to find
putting all these value in equation
so
