AI Technical Summary
Traditional forming processes produce ceramic/titanium alloy composites with problems such as coarse grains, ceramic powder agglomeration, and low interfacial bonding strength, making it difficult to meet the harsh working conditions such as high temperature, high pressure, large load, and strong corrosion.
A titanium-based composite material with B4C+RE synergistic reinforcement was prepared by using laser melting deposition technology combined with ball milling and post-heat treatment. The uniform distribution and high bonding strength of the reinforcing phase in the titanium matrix were achieved through in-situ self-generated TiB, TiC and rare earth oxide reinforcing phases.
It significantly improves the tensile strength, surface friction coefficient and microhardness of titanium-based composite materials, reduces corrosion current density, and exhibits excellent comprehensive performance.
