摘　　要：用粉末冶金法制备了Fe3Al基复合材料,对其抗氧化行为和磨损机理进行了分析研究,发现无论是做热氧化性实验,还是高速重载摩擦磨损实验,它的抗氧化性行为主要是在Fe3Al颗粒表面形成氧化铝保护膜,该膜阻断氧原子的进一步侵入而提高了该材料的抗氧化性,该材料的主要磨损形式是磨粒磨损。Fe3Al matrix composite material was prepared by powder metallurgy technology. Study on the anti-oxidation property and abrasion mechanism of Fe3Al matrix composite material was carried out. it has been found that, either hot-oxidation test or high rotating and heavy load test of friction and abrasion, Al2O3 protecting film formed played a vital role in anti-oxidation process, which can prevent oxygen atom from invading inner of composite and improve anti-oxidation of the composite. The abrasion mechanism of the composite was mainly abrasive wear.
