在Mo粉中添加1.0%SiC，通过行星式球磨机混料使其分布均匀，球磨机转速为350 r/min，然后分别以300、500、1000、1500MPa的压力压制成型后在1400℃的氢气气氛炉中烧结，采用HVS-1000型显微硬度计，在测试前将试样磨平并抛光，并保证样品上下表面平行，所有的测试压力为1.0 kg，保压时间为10 s，选择试样平整面测硬度。

1.0% SiC was added to Mo powder, and the material was mixed by planetary ball mill to make uniform distribution, and the ball mill speed was 350 r/min, then pressed and shaped at 300, 500, 1000 and 1500 MPa respectively and then sintered in a hydrogen atmosphere furnace at 1400°C. The HVS-1000 micro hardness tester was used, and the specimens were ground and polished before testing, and it was ensured that The upper and lower surfaces of the sample were parallel, all the test pressures were 1.0 kg, and the holding time was 10 s. The flat surface of the specimen was selected for hardness measurement.
