摘要：

This paper presents the synthesis and the characterisation of various chromium carbide compounds, Thin Cr23C6 films were deposited by reactive sputtering while Cr7C3 films were formed by the carburisation of chromium films in a CH4/H-2 atmosphere, CrxCy powders were synthesised from various precursors (Cr, CrN, Cr2O3) by reaction with CH4/H-2 at high temperature. The samples were characterised by AES, XRD and electron diffraction. The effects of the experimental parameters (gas composition, temperature, reaction time) on the purity, the phase formed and the composition of the product of reaction are examined and discussed.
