摘要

采用热压成形法制备了FeCrMoCBY非晶/酚醛树脂复合材料，探究不同含量的非晶颗粒对复合材料性能的影响。结果表明，添加非晶颗粒后复合材料的硬度提升，其中非晶添加量为30%和40%的试样硬度(HRB)分别为68和74.3。随非晶合金含量增加，其摩擦因数呈先上升而后回落的趋势，体积磨损率逐渐降低，磨损机制由磨粒磨损转变为粘着磨损和磨粒磨损共同作用的混合机制。随着试验温度升高，复合材料的摩擦因数逐渐降低，体积磨损率逐渐增加。

Abstract

FeCrMoCBY amorphous/phenolic resin composites were prepared by hot press forming

and the effects of different content of amorphous particles on the properties of composites were explored. The results indicate that the hardness of the composites is enhanced after the addition of amorphous particles

of which the specimens with an amorphous addition of 30% and 40% are 68 HRB and 74.3 HRB

respectively. With the increase of the amorphous content

the average friction coefficient is firstly increased and then decreased

and the volume wear rate is gradually decreased. The wear mechanism is transformed from abrasive wear to a mixed mechanism of adhesive wear and abrasive wear. As the test temperature increases

the average friction coefficient of the composite is gradually decreased

and the volume wear rate is gradually increased.
