In high-temperature environments, titanium alloy wire for aerospace applications readily reacts with oxygen, forming an oxide layer. High-Temperature Oxidation Performance Tests expose titanium alloy wire to a high-temperature oxidizing environment, measuring its oxidation weight gain and oxide layer thickness to assess its oxidation resistance. Good oxidation resistance can extend the service life of titanium alloy wire in high-temperature environments and reduce the risk of performance degradation and failure due to oxidation.
High-Temperature Fatigue Performance Tests
Aerospace equipment is often subjected to cyclic loading during operation. High-Temperature Fatigue Performance Tests simulate the fatigue life and crack growth behavior of titanium alloy wire under high-temperature cyclic loading using a high-frequency fatigue testing machine, assessing its durability under high-temperature alternating stress. This is crucial for ensuring the reliable operation of aerospace equipment under complex loading conditions.
