摘要

采用电磁搅拌技术制备了B

/Al复合材料

并对B

C颗粒进行了预处理

利用MMW-1A型磨损试验机对复合材料进行磨损试验

研究材料的磨损性能及机制。结果表明

C颗粒预处理可有效去除颗粒中混杂的杂质金属;当电磁搅拌强度为60%

搅拌频率为20Hz

搅拌时间为15min

陶瓷颗粒含量为3.5%时

具有良好的磨损性能。在磨损过程中

随着磨损时间延长

其磨损机理随之变化

由单一的剥层磨损最后变为氧化磨损、粘着磨损以及磨粒磨损等多种制机共同作用。

Abstract

/Al composites were prepared by electromagnetic stirring technology

in which B

C particle were pretreated.The wear properties and mechanism of the composites prepared were investigated by wear test on MMW-1 Awear tester.The results reveal that the impurity metal mixed in the particles can be effectively removed by pretreatment for B

C particles.The composites prepared present the satisfied wear resistance with electric stirring intensity of 60%

stirring frequency of 20 Hz

stirring time of 15 min and particle content of 3.5%.During the wearing process

with the increase of wear time

the wear mechanism is changed from palling wear to the comprehensive effect of oxidative wear

adhesive wear and abrasive wear.
