WC/Co含量对Ni-WC/Co纳米复合镀层摩擦学性能的影响
|
摘要
为了探究Ni-WC/Co纳米复合镀层对材料表面摩擦学性能的影响,采用脉冲电沉积制备出Ni-WC/Co纳米复合镀层,研究镀液中WC/Co含量对复合镀层晶体结构、晶粒尺寸和硬度的影响;室温下,在MM-W1B立式万能摩擦磨损试验机上测试复合镀层的摩擦学性能,分析其磨损机理。结果表明:随着镀液中加入WC/Co颗粒含量的增加,复合镀层平均晶粒尺寸先减小后增大,硬度则是先增大后减小,镀层的摩擦系数和磨损速率都是先降低后升高;当WC/Co含量为30.0 g/L时,复合镀层的平均晶粒尺寸最小,硬度最高,摩擦系数和磨损速率最低,耐磨性能最佳,复合镀层表面只呈现出轻微划痕,是由磨料磨损造成的,没有犁削和黏着磨损的特征。
In order to explore the effect of Ni-WC/Co nanocomposite coating on the tribological properties of the surface of the material,the Ni-WC/Co nanocomposite coatings were prepared by pulsed electrodeposition. The effect of WC/Co content on the crystal structure,grain size and hardness of the nanocomposite coatings was studied. At room temperature,MM-W1 B vertical universal friction and wear tester was employed to test the tribological properties of nanocomposite coatings,and the wear mechanism was analyzed further. Results showed that with the increase of WC/Co content,the average grain size of the nanocomposite coating decreased firstly and then increased,and meanwhile the hardness increased firstly and then decreased. Moreover,the friction coefficient and wear loss of the coating reduced first and then increased.When the WC/Co content was 30.0 g/L,the nanocomposite coating had the smallest average grain size,the highest hardness,the lowest friction coefficient and wear loss,and the best wear resistance. Besides,the surface of the nanocomposite coating was only slightly scratched due to abrasive wear,and there was no plowing and adhesive wear characteristics.
