The influence of chemical reaction parameters on the interaction of thermal, diffusion and mechanical waves under surface treatment by a particle beam

A coupled non-isothermal model of the penetration process a material into target surface under conditions treatment with particle beam is presented. The takes account interaction impurity diffusion, heat propagation, mechanical disturbances and chemical reaction between introduced substrate material. problem formulated in terms dimensionless variables. All parameters range numerical values are given. solved numerically using an implicit symmetric difference scheme second order approximation time coordinates. solutions obtained for different intervals determined by characteristic pulse action relaxation times diffusion thermal conductivity. It has been established that interrelation processes scales leads to appearance distortions on strain stress waves, distributions temperature concentration acquire wave character. formation compound decrease impurities increase temperature, stresses deformation. shown at low generation proceeds only as long increases due energy. found that, slow product reaction, practically does not affect propagation deformation, concentration.
