Embodiment 1
[0022] The preparation method of the present embodiment stainless steel fiber sintered felt comprises the following steps:
[0023] Step 1. Place the stainless steel fiber felt in a vacuum sintering furnace at a vacuum degree of ≤1×10 -2 Under the condition of Pa, the stainless steel fiber felt is heated up to 400°C at a heating rate of 10°C / min and then kept for 60 minutes for low-temperature sintering treatment, and the low-temperature sintered felt is obtained after natural cooling; the stainless steel fiber in the stainless steel fiber felt is preferably made of a bundled 316L stainless steel fiber prepared by drawing method, the fiber diameter is 28 μm;
[0024] Step 2. Use a hydraulic press to compress the low-temperature sintered felt in step 1 to a porosity of 83%, and then place the compressed low-temperature sintered felt in a vacuum sintering furnace at a vacuum degree ≤ 1×10 -2 Under the condition of Pa, the compressed low-temperature sintered felt was heated up t...
