Abstract

The invention discloses a titanium-based tungstenic alloy material used for 3D printing. The material contains tungsten carbide, nickel, niobium, vanadium, copper, molybdenum and titanium. A preparation method comprises the steps that metal powder is fully mixed after component design is completed; the mixed powder is subjected to sintering and alloy homogenizing; and then alloy powder is obtained through mechanical alloying. A 3D printing finished product of the obtained material has the advantages of being low in weight, high in high-temperature hardness, excellent in high-temperature abrasion resistance, and resistant to corrosion.

Description

technical field [0001] The invention relates to the field of metal powder preparation, in particular to a titanium-based alloy material for 3D printing containing tungsten and a preparation method thereof. Background technique [0002] The core of 3D printing technology is equipment and materials. With the development of 3D printing technology, 3D printing equipment is mature, but currently there are few types of materials available for 3D printing and unstable performance, which has become a bottleneck problem restricting the development and application of 3D printing technology. The metal powder materials used in traditional powder metallurgy cannot fully adapt to the 3D printing process. At present, there are few types of metal powders, high prices, and low degree of productization. [0003] Titanium alloy has excellent comprehensive properties such as low density, high specific strength, high specific stiffness, corrosion resistance, high temperature mechanical properti...
