Description

technical field

[0001] The invention relates to the field of metal powder preparation, in particular to a TiB used for additive manufacturing 2 A preparation method for reinforced aluminum alloy powder. Background technique

[0002] With the development of science and technology, aerospace, weaponry and other fields put forward new requirements for light-weight and high-strength load-bearing structures, but these structures are often complex in design, cumbersome in processing procedures, and require high precision, which cannot be met by traditional production processes. processing requirements for these structures.

[0003] Laser selective melting additive manufacturing technology (SLM) can effectively solve the manufacturing bottleneck of traditional processes, but aluminum alloy has high laser reflectivity and low absorption rate, which has always been one of the most difficult materials for SLM. At present, the powder materials for aluminum alloy SLM additive manufact...
