摘要
研究了用粉末热锻工艺制备耐热铝基复合材料的过程以及SiC颗粒增强Al -Fe -V -Si耐热铝基复合材料的力学性能和室温、中温耐磨性。研究结果表明 ,SiC颗粒提高了复合材料强度和耐磨性 ,在 2 50℃以下为轻微磨损 ,达到 30
The processing of powder hot forging to producing high thermal aluminium composite have been studied, as well as the strength and wear stability of SiC particlulate reinforced Al-Fe-V-Si heat resistant aluminium. It was found by the study that the sthength and wear stability of the composite were improved by SiC particulate. The composite was slightly tribodeformed below 250℃, but urgently tribodeformed on 300℃ as wear mechanism changed.
