Influence high energy proton irradiation on structurе and stress-strein state ion-plasma coating quasi-binary system TIC-WC

Abstract

Using wide angle X­ray diffraction methods in conjunction with tensometry studied the effect of proton ir radiation of ion­plasma coatings quasi­binary system TiC­WC.na change their characteristics in the triad phase composition — structure (substructure) — stress­strain state. Found that used qua si­binary system is stable in its phase­structural characteristics to irradiation with protons with an en ergy of 200 keV to a dose of 6.5·1017 cm–2. Significant changes under irradiation occur only in stress­strain state.  Physical reasons for the effects observed have been discussed.
