Mathematical modeling of heat transfer at high-speed electron-beam evaporation of metals and vapor deposition on moving band-substrate

摘要

A mathematical model of heat transfer has been developed at high-speed electron-beam evaporation of materials and vacuum deposition of vapors on moving band-substrate designed for calculation of the temperature conditions of condensate formation. Taking account of band movement, heat transfer along its length and width as well as using the diagrams of direction of radiation and vapor fluxes appropriate to a model of isothermal crater that is formed on the surface of the melt during evaporation is a feature of the model.
