Abstract

This study investigates the feasibility of producing thick condensed TiC-based materials through high-rate electron-beam evaporation–condensation of graphite and titanium in vacuum. The research determines the dependences of density, porosity, and microhardness of both as-deposited and annealed condensates, subjected to a temperature of 1000°C, on the substrate temperature. The analysis of mechanical properties as a function of carbon content in TiC condensates demonstrates that the flexural strength reaches its maximum at a carbon concentration of 12–14 wt %, while microhardness peaks at 18–20 wt %.
