The diffusion of zirconium and copper deposited on a flat graphite surface after annealing at 898 K for 1800 s and 1233 K for 300 s was studied by glow discharge optical emission spectrometry. At the temperature of 898 K no mutual diffusion of Zr and Cu appears. At the temperature of 1233 K Zr diffuses into Cu, and a zirconium containing phase at the contact with carbon may occur. The obtained results have a qualitative character and are discussed in connection with the influence of zirconium on the thermal conductivity of the Cu-Zr matrix.
