AI Technical Summary
Existing 3D printing technology is prone to defects such as holes and cracks when preparing multi-layer metal components, and it cannot solve the problem of inner metal structure, especially under ultra-high pressure environment, the presence of welds cannot be avoided.
Using a titanium-aluminum alloy tube as the skeleton, the outer surface is coated with metal powder to form a coating layer. It is then metallurgically solidified through cold isostatic pressing and vacuum heat treatment furnace to form multi-scale, multi-layer metal components, avoiding welding. The positive pressure generated by the thermal explosion reaction of the Ti+Al powder mixture inside the titanium-aluminum alloy tube and the protection of the outer hard shell are utilized.
It enables the molding of multi-scale, multi-layer metal components, which can be weld-free under ultra-high pressure, with complete structure, cost savings, and simplified process.
