Abstract

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.
