Embodiment 1
[0032] Example 1: A 3D printing ternary boride Mo provided in this example 2 NiB 2 Alloy powder and its production process, see figure 1 , the process steps are as follows:
[0033] (1) Ingredients: wet ball milling has more obvious advantages in terms of particle size distribution, anti-oxidation of powder, segregation and agglomeration of powder for preparing powder, so wet ball milling process is preferably used in this embodiment. Prepare the materials and their mass percentages as follows: B 3.3%, Mo 50%, Cr 10%, C 2%, V 0.5%, Nb 2%, W 0.5%, Ce 2%, Mn 4%, Ta0.3%, Ti 0.6%, binder 3%, Ni23%;
[0034] (2) Rod making: mix raw materials B, Mo, Cr, C, V, Nb, W, Ce, Mn, Ta, Ti, Ni and binder according to the formula. The binder is preferably paraffin. In other embodiments, the binder can be selected from PEG, rubber or resin, etc.; mixed with any one or more solvents such as absolute ethanol or methanol, acetone, n-heptane, n-hexane, etc. The azeotropic solvent is used as t...
Embodiment 2
[0041] Embodiment 2: A kind of 3D printing ternary boride Mo provided by this embodiment 2 NiB 2 Alloy powder and its production process are basically the same as in Example 1, except that the elements and their mass percentages are as follows: B 7%, Mo 25%, Cr 15%, C 1%, V 5%, Nb 3%, W 4%, Ce 0.5%, Mn 1%, Ta 1%, Ti 2%, binder 6%, Ni 29.5%.
Embodiment 3
[0042] Embodiment 3: A kind of 3D printing ternary boride Mo provided by this embodiment 2 NiB 2 Alloy powder and its production process are basically the same as in Example 1, except that the elements and their mass percentages are as follows: B 5%, Mo 30%, Cr 4%, C 0.5%, V 3%, Nb 1.5% , W 6%, Ce 0.6%, Mn 3%, Ta 0.7%, Ti 0.7%, binder 4%, Ni41%.
