AI Technical Summary
The low hardness, poor wear resistance and high coefficient of friction of titanium alloys limit their application in sliding and friction conditions. Existing surface strengthening technologies are difficult to achieve uniform coating coverage for complex-shaped components and are costly. Furthermore, composite materials suffer from ceramic particle agglomeration and uneven composition distribution when forming complex contour workpieces.
By depositing amorphous ceramic thin films on the surface of titanium alloy powder, selective melting technology is used to induce in-situ reactions between titanium elements and elements in the amorphous ceramic thin film to generate nano-reinforcing phases (TiC, TiB, TiN). The uniform distribution of the ceramic phases is achieved through additive manufacturing. High wear-resistant titanium-based composite materials are prepared by combining thin film deposition technology and additive manufacturing technology.
The prepared titanium-based composite materials have broad application prospects in aerospace, transportation and other fields. They have excellent comprehensive mechanical properties, high wear resistance and molding quality, and are suitable for use in extremely harsh working conditions.
