The method of forming crystalline nanoporous oxide on a titanium-aluminum alloy

摘要

1. A method of forming crystalline nanoporous oxide on a titanium-aluminum alloy, comprising manufacturing a part from a sintered titanium-aluminum alloy powder with a grain size of 1-10 μm, washing the part in ethanol, drying, washing in distilled water, drying at a temperature of 80-90 ° C, the formation of nanoporous oxide on the surface of the part by anodizing in ethylene glycol with the addition of 0.25% NHF at room temperature and a constant voltage of U = 60V and heat treatment in air at a temperature of 800-820C for 30-40 min. 2. The method according to p. 1, characterized in that the heat treatment is carried out in vacuum at a pressure of (10-10) mm Hg
