Modification of a titanium surface layer with yttrium is performed by a combined method providing electroexplosive alloying and subsequent treatment by a high-intensity electron beam. Alloyed layer elemental and phase composition, defect substructure, mechanical and tribological properties are determined. Saturation of a titanium surface layer with atoms of yttrium, oxygen, and carbon is revealed,...
Wetting and contact interaction have been examined for the nitrides TiN0.98 and ZrN0.87 in contact with chromium -nickel alloys of various compositions at 1500-1900°C in purified argon at an excess pressure of 0.35·105 Pa; the methods used have been sessile drop, microstructure, x-ray diffraction, electron-probe microanalysis, and hardness measurement. Wetting is accompanied by interaction of the...
