摘要:

在SiO2基体上分别制备了纳米结构(非晶及石墨烯纳晶)碳膜,利用自主设计的多物理场耦合往复式摩擦学实验装置,研究了不同纳米结构的碳膜在温度电场耦合作用下的摩擦学特性。室温下,纳米结构碳膜摩擦因数的主要影响因素为电场;摩擦副温度为200 ℃时,纳米结构碳膜摩擦因数的主要影响因素为温度。温度电场耦合作用下,非晶碳膜的纳米结构向纳晶结构转化,摩擦因数减小;石墨烯纳晶碳膜结构稳定,但碳膜磨损加剧导致摩擦因数波动较大。

Abstract:

The nanostructured carbon films including amorphous carbon films and graphene nanocrystalline carbon films were prepared on SiO2 substrates. A self-designed reciprocating tribometer capable for applying coupled multi-physical fields was employed to investigate the tribological properties of the different nanostructured carbon films under the coupling effect of temperature and electric field. At room temperature, the electric field was the dominant factor for affecting the friction coefficient of nanostructured carbon films. When the temperature of tribopair was 200 ℃, temperature became the main influencing factor. Under the coupling effects of temperature and electric field, the structured evolution to graphitic-like structure leads the reduction of friction coefficient of amorphous carbon film. While the nanostructure of graphene nanocrystalline carbon film is stable, but the aggravated wear results in significant fluctuations of friction coefficient.

Key words: carbon film, tribological property, nanostructure, temperature, electric field
