Abstract : A new derivation of transport properties in a two-temperature plasma has been performed. The electron kinetic temperature Te is supposed to be different from that of heavy species Th. The resolution of the Boltzmann-s equation, thanks to the Chapman-Enskog method, is used to calculate transport coefficients and it allows to the generalisation ofbracket integrals out of thermal equilibrium. Two-temperature diffusion coefficients are defined and the obtained results are presented for an atmospheric two-temperature argon plasma.
