Simulation of deuterium reflection from plasma-sprayed tungsten
A method of computer simulation of the formation of plasma-sprayed tungsten surface is proposed. The dependencies of the reflection coefficients of hydrogen isotopes on the energy of incident particles in the range from 5 to 104 eV were obtained for this surface. It is shown that, at energies about 10 eV, the reflection coefficient for the surface of plasma-sprayed tungsten is smaller than that for a smooth surface by a factor of 1.5; this decrease corresponds to the increase in the deuterium incorporation coefficient by a factor of 2.
