  The work is devoted to modeling of the processes occurring in ion-plasma
treatment of polyurethane and forming on its surface a special carbonized
layer. The mechanisms affecting the formation of wave-like relief in the
carbonized layer are examined. The boundary value problem for the heat equation
for modeling the effect of temperature component was solved. Using the finite
element method the deformation of the polyurethane sample during ion-plasma
treatment was calculated. On the basis of calculations conclusion about the
impact of these factors on the formation of wave-like relief in the carbonized
layer was made.
