采用等离子喷涂技术在45钢基体表面上制备了4种不同MoS_2含量(0%,3%,6%,9%)的AT13/MoS_2复合涂层,研究了不同MoS_2含量的AT13/MoS_2复合涂层的磨损表面形貌和涂层的摩擦学性能。结果表明,随着MoS_2含量的增加,复合涂层的摩擦因数逐渐降低,但当MoS_2含量为6%时,复合涂层的体积磨损量最低,涂层的综合性能最好;AT13涂层的磨损机理主要是磨粒磨损,随着MoS_2含量的增加,复合涂层的磨损机理由疲劳磨损和摩擦磨损向磨粒磨损转变。

AT13/MoS2 composite ceramics coating with four different MoS2 contents (0%, 3%, 6%, 9%) on 45 steel surface were prepared by plasma spraying, and the microstructure structure after wearing and tribological properties of AT13/MoS2 composite coatings were investigated. The results show that the friction coefficient of composite coatings decreases with the increase of MoS2, while the volume loss of composite coating is the lowest when the content of MoS2 is 6%,meanwhile the comprehensive performance of composite coating is optimal. The wear mechan...
