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 
Yes, it will. The induction will be the same as long as it’s put back together.
