中文摘要:
      为了提高低碳钢的耐磨性,成功地采用等离子体电解碳氮共渗技术在不同电压下对低碳钢进行表面处理。使用往复式摩擦磨损测试仪分析改性表面的摩擦磨损性能;SEM和EDS分析渗透层的表面,截面形态和组成;使用3D共聚焦显微镜分析渗透层的磨痕;使用XRD研究渗透层的相组成。结果表明:共渗层的厚度和显微硬度均随着施加电压的增加呈现出先升高后降低的趋势,在电压为350V时,共渗层厚度最厚,硬度最大,分别为130.24μm和846.7HV;此时共渗层的摩擦系数最小,约为0.65,磨痕轮廓深度仅为14.79μm。液相等离子体电解渗技术在共渗层形成的铁碳化合物和铁氮化合物是其耐磨的主要原因。
英文摘要:
      In order to improve the abrasion resistance of low carbon steel, plasma electrolytic carbon-nitriding(PECN) was successfully used to achieve surface treatment on low carbon steel at different voltages. The ball-on-disc reciprocating friction and wear tester was used to test the friction and wear performance of the modified surface. SEM and EDS were used to analyze the morphologies and composition of the surface and cross-section of the osmotic layer. 3D confocal microscope was used to analyze the wear scar profile of the osmotic layer. XRD was used to investigate the phase composition of the osmotic layer. The results show that the thickness and micro-hardness of osmotic layer first increase and then decrease as the voltage increases. When the voltage is 350V, the thickness and the hardness of the osmotic layer is the largest, which are 130.24μm and 846.7HV. In the meantime, the friction coefficient of the osmotic layer is the smallest, about 0.65, and the depth of the wear scar profile is only 14.79μm. The iron carbon compounds and iron nitrogen compounds formed by the plasma electrolytic carbon-nitriding technology in the osmotic layer are the main reasons for their wear resistance.
