Abstract: Three kinds of ceramic films were coated on aluminum alloy by process of plasma enhanced electrochemical surface of ceramic coating(PECC). The results show that thermal conductivity of films have particular characteristic. With the varying temperature, thermal conductivity of films varies greatly: at 20 200�@℃, thermal conductivity of white film varies in the range of 15.28 21.02�@W/(m·K); thermal conductivity of black film varies in the range of 9.49 14.75�@W/(m·K); thermal conductivity of blown film varies in the range of 35.02 51.91�@W/(m·K).
