| Summary: | Title screen Experimental data of the physical-mechanical characteristics for two systems hard nanocrystalline coatings TiAlN and TiAlSiN are presented. These coatings were deposited under similar condition on the steel sample 12Ch18N10T and the hard alloy sample WC-8. It was adjusted correlation between parameters W (the elastic recovery), H/E (the elastic failing deformation), H 3/E 2 (the material resistance to the plastic deformation). Also the mathematic model of the dynamic coating growth with movement boundary was constructed. Here is according to the experiment data [2], the growth rate of nitride coating corresponds to predetermined parameters of a vacuum-arc device. It is assumed that the rate of coating growth is determined by technological parameters due to the directed flux of aluminum and titanium or silicon positive ions from the cathode. Interstitial impurities penetrate plasma coating, thus nitride coating synthesis runs in the diffusion mode. Coating growth dynamics is described by one diffusion equation with different coefficients for the coating and the substrate. The task is calculated numerically and different schemes and variable time steps are used. Режим доступа: по договору с организацией-держателем ресурса |
