MECHANISM OF HIGH-TEMPERATURE OXIDATION OF CLAD COMPOSITES BASED ON TITANIUM DIBORIDE

摘要

The authors have studied the resistance of composites based on nickel- and copper-clad titanium diboride to high-temperature oxidation in air. It is demonstrated that copper cladding has no significant effect on the process of oxidation of the composites, while nickel cladding increases the initial temperature of their intensive oxidation by 150℃. This fact enables composites based on nickel-clad titanium diboride to be recommended for the use as wear- and corrosion-resistant coatings to be applied by gas-thermal spraying.
