The calculation of the enhancement factor for the rate of thermonuclear reactions in the strong-screening regime is extended to the cases involving plasmas with two different ion species. The calculation is based on the recent results of Monte Carlo computations for such two-component plasmas. With appropriate definition and combination of the plasma parameters we find that the screening potentials in two-component plasmas exhibit a linear dependence at intermediate distances, quite similar to that found for one-component plasmas. Application to the calculation of carbon ignition in the carbon--oxygen core of a highly evolved star is discussed.
