The results of producing an Al2O3 composite coating on titanium by electron-beam cladding in the forevacuum pressure range (3…30 Pa) are presented. The microstructure, phase composition, and mechanical properties of the resulting composite layer were investigated. Using scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray diffraction analysis, it was found that the coating consists predominantly of the ?-phase of Al2O3 (82 %), along with ?-Ti and cubic TiO. The average surface microhardness reaches 13.6 GPa, which is five times higher than that of the uncoated titanium. It was shown that preliminary outgassing of the powder by electron-beam irradiation ensures process stability and the formation of a dense composite layer. The obtained results demonstrate the promise of the developed method for creating ceramic coatings on titanium.
