摘 要: 采用多弧離子鍍技術(shù)在硅片和316L不銹鋼上制備了CrN和CrCN涂層，利用掃描電鏡(SEM)、電子能譜(EDS)、透射電鏡(TEM)、X射線光電子能譜儀(XPS)對(duì)其表面形貌及成分進(jìn)行表征，采用納米壓痕儀、劃痕測(cè)試儀及摩擦磨損試驗(yàn)機(jī)測(cè)試涂層力學(xué)及摩擦學(xué)性能，觀察試樣磨損形貌，并分析其磨損機(jī)理。結(jié)果表明：較之于CrN涂層，所制備的CrCN涂層具有更均勻、致密的結(jié)構(gòu)，與基體結(jié)合良好；涂層主要成分為Cr、C和N，其中C元素主要以sp2、sp3和C—Cr鍵的形式存在；CrCN涂層中由于強(qiáng)化相Cr7C3的產(chǎn)生和雜化C的形成等多種強(qiáng)化作用，顯著提高了其硬度和耐摩擦磨損性能。

Abstract:CrN and CrCN coating were prepared on single crystal Si and 316L stainless steel by arc ion plating. The surface morphology, microstructures, phase compositions and performance of the CrCN coating were characterized by SEM, EDS TEM, XRD, XPS, EDS, nanoindentation, scratch test and wear tester. The surface morphologies after wear were observed and the wear mechanism was discussed. The results show that CrCN coating has obvious flaws and better bond with the matrix than CrN coating. The composition of CrCN coating mainly contains Cr, C and N. sp2, sp3 and Cr—C bonds dominate in the carbon bonding. Because of the reinforced Cr7C3 particulate and the formation of hybrid carbon, the hardness, tribological properties and wear resistant of CrCN coating can be enhanced.
