Reciprocating friction experiments were conducted to determine the effect of temperature (20°C-300°C) on the friction characteristics of silicon-based ceramics slid against pure metals. After the sliding experiments were performed, metal transfer to the ceramic surfaces was also investigated.<br>Up to 100°C, the friction coefficient of SiC was lower than that of Si<sub>3</sub>N<sub>4</sub>. The friction coefficients of both ceramics rose at over 200°C, however the difference between SiC and Si<sub>3</sub>N<sub>4</sub> became negligible.<br>At 20°C, chemically more active metals showed higher friction coefficients against Si<sub>3</sub>N<sub>4</sub>. The friction coefficients of all metals became higher as the temperature rose, especially against SiC. The friction coefficients for Ag against both ceramics were extremely high, for example, at temperatures over 200°C they exceeded 2.0.<br>Except for Ag and Mo, the pure metals used in this study transferred to the ceramic surfaces. Transfer occurred when the shear strength of the pure metal substrates was weaker than that of the metal oxides.
