摘要
类金刚石薄膜(Diamond-Like Carbon,DLC)因其优异的润滑耐磨性能在多个领域备受关注。本文系统综述了磁控溅射技术在DLC薄膜制备中的研究进展,重点探讨了工艺参数及元素掺杂对薄膜性能的调控机制。首先,分析了气体流量比、偏置电压和电流等关键参数对DLC薄膜微观结构及摩擦学性能的影响:通过优化气体流量比(如Ar/CH4)可调控sp^(2)/sp^(3)键比例,降低摩擦系数;控制偏置电压能够平衡薄膜硬度与表面缺陷;调节电流则直接影响离子通量及sp^(3)键稳定性。其次,总结了非金属(Si、N、F)与金属(Cr、Ti)元素掺杂的作用机理:Si掺杂增强高温稳定性并降低残余应力,N掺杂促进石墨化结构形成,F掺杂通过C-F键钝化表面悬键;Cr和Ti的引入则通过碳化物相抑制氧化并优化力学性能。最后对DLC薄膜技术的未来发展前景进行了展望。
Diamond-like carbon(DLC)films have drawn considerable attention in various fields due to their excellent lubricating and wear-resistant properties.This paper systematically reviewed the research progress of magnetron sputtering technology in DLC film preparation,with emphasis on the regulating mechanisms of process parameters and elemental doping on film performance.Firstly,the effects of key parameters including gas flow ratio,bias voltage and current on the microstructure and tribological properties of DLC films were analyzed:optimizing gas ratios(e.g.,Ar/CH4)could regulate the sp^(2)/sp^(3) bond ratio to reduce the friction coefficient;bias voltage control could balance film hardness and surface defects;current adjustment directly affected the ion flux and sp^(3) bond stability.Secondly,the doping mechanisms of non-metal(Si,N,F)and metal(Cr,Ti)elements were summarized:Si doping enhanced high-temperature stability and reduced residual stress;N doping promoted graphitic structure formation;F doping passivated surface dangling bonds through C-F bonds;while Cr and Ti incorporation inhibited oxidation through carbide phases and optimized mechanical properties.Finally,the development prospects of DLC film technology were prospected.
