COMPOSITE MATERIAL AND METHOD FOR IMPROVING FATIGUE PROPERTIES OF TITANIUM ALLOY BY COATING METALLIC GLASS LAYER

摘要

The invention provides a composite material, which includes a titanium alloy substrate and a metallic glass layer. The metallic glass layer is disposed on the titanium alloy substrate. The thickness of the metallic glass layer is 50 nm-200 nm, in which in comparison with the titanium alloy substrate, the fatigue life of the composite material of the invention is increased by 5-17 times.
