Description/Abstract It has been demonstrated that it is feasible to form a dense, pore-free coating of yttria stabilized zirconia on a porous graphite substrate by electrochemical vapor deposition.^It appears that under appropriate conditions the structural integrity of the composite may be retained during slow heating and cooling, in spite of the gross mismatch in the thermal expansion coefficients of the coating and substrate.^It is hypothesized that the thermal expansion difference is accommodated in the tetragonal zirconia phase by the preferential alignment of the c-axis along the pinacoidal direction closest to the interfacial plane via a displacive transformation during cooling.
