Embodiment 1
[0022] This embodiment includes the following steps:
[0023] Step 1. Pre-compressing the accumulated titanium chips along the thickness direction at room temperature to obtain a titanium-based porous green body; the porosity of the titanium-based porous green body is 80%;
[0024] Step 2. Place the titanium-based porous green body obtained in step 1 in a vacuum furnace at a temperature of 1200° C. and a vacuum degree of 1×10 -2 Under the condition of Pa, heat preservation for 2 hours for high-temperature vacuum sintering, so that the node parts in the titanium-based porous green body are metallurgically bonded, and the titanium-based porous green body is obtained after cooling;
[0025] Step 3, inject 502 glue into the pores of the titanium-based porous body obtained in step 2 at room temperature to fill each node area, and obtain a titanium-based porous material after drying at room temperature; the equivalent pores of the titanium-based porous material The degree is 70%. ...
