Computer simulation of thermal fields of the Cr-Mo-Zr system for coating formation using a low-energy high-current electron beam

Abstract

The paper presents the results of calculations of temperature fields in the system film(Cr)/film(Mo)/substrate(Zr) under pulsed electron-beam impact. The melt thicknesses of the system elements as a function of the NSEP energy density were calculated for Cr film thicknesses of 0.5, 1.0, 2.0 and 3.0 μm and Mo intermediate film thickness of 1.0 μm. In this work, the influence of the energy characteristics of electron beam impact on the thickness and melt lifetime is investigated. It is obtained that the melt lifetimes of Cr, Mo films and Zr substrate depend significantly on the LEHCEB energy density and chromium film thickness.
