Pushing the limits of Heat Endurance
Due to good high temperature stability, high corrosion resistance and specific strength, Ti64 is one of the most widely used titanium alloys, accounting for more than 50% of the titanium usage worldwide. Ti64 was used in industry since 1950s and has been widely used in aerospace, biomedical and automotive fields. However, the relatively low wear resistance, low heat resistance and low fatigue endurance of Ti64 are the major drawbacks, limiting its widespread application in industrial fields especially in additive manufacturing.
Thermal resistance is also considered as an important factor for material selection in critical parts mainly in aerospace and automotive. The thermal oxidation of Ti64 generally starts around 270 °C resulting in a color change from gray (natural color of Ti64) to black color depending on temperature. This drawback is due to the low thermal resistance of Ti64. However, ZTP10 was designed to resist high temperature oxidations
