Embodiment 1
[0030] This embodiment provides a method for preparing a highly active titanium-based tantalum coating with a micro-nano multi-level structure, comprising the following steps:
[0031] 1) Select tantalum powder (w(Ta)≥99.5%) with a particle size of 45-105μm as the raw material for spraying, and the powder appearance is as follows figure 1 As shown, the powder is spherical and has good fluidity; the powder is dried at 60°C for 30 minutes, and cooled for later use.
[0032] 2), using Al 2 o 3 The powder is subjected to sandblasting pretreatment on the titanium-based material. The sandblasting pressure is 0.8MPa, and then ultrasonically cleaned with acetone, ethanol and deionized water for 15 minutes, dried at 60°C for 30 minutes, and cooled for later use;
[0033] 3), using atmospheric plasma spraying technology, spray the tantalum powder prepared in step 1) onto the surface of the titanium-based material after sandblasting in step 2), and prepare a tantalum coating with a thi...
