Consider a compound wall is made of two materials A and B of thickness d1 and d2.  Let K1 and K2 be the coefficients of thermal conductivity of the two materials. Let  01 and 02 be the temperatures of the end faces ( 01  > 02 ) and '0' is the temperature of surface joining two materials. Using the relation for the amount of heat conducted per second across any cross section, bring out the expression for the temperature at the interface between two materials.

Q = (KA (01 -  0)/d)    -   Use this format of equation for the two materials and arrive at the equation for the temperature  '0' at the interface joining A and B.
