The cylinder engine surface texture has a major influence on the functional performances of the ring-pack tribo-system. The cylinder engine surface microtexture manufactured by plateau honing (PH) and helical slide honing (HSH) processes have been analyzed using white light interferometry (WLI), and stereometric analysis. The approaches in three-dimensional (3-D) white light interferometer measurements and surface stereometric analysis are important for the correct interpretation of 3-D local surface texture features and can be applied in mathematical models for calculating the friction. The samples were divided into two groups: plateau honing (PH) samples and helical slide honing (HSH) samples to discuss the obtained results, according to the honing techniques obtained after several stages: the rough and finish honing and final stage. The obtained results demonstrated that the surface of group PH has the higher values of root mean square height (Sq = 1.83 μm) and fractal dimension (Df = 2.74 ± 0.01), while the lowest values of root mean square height (Sq = 0.63 μm) and fractal dimension (Df = 2.60 ± 0.01) were found for HSH samples. These values highlight that the PH samples are more irregular (both as surface and topography) in comparison with HSH samples. HIGHLIGHTS: We characterized the micromorphology of surface microtexture in plateau and helical slide honing. The nanostructure morphology was investigated using the white light interferometry, fractal and stereometric analyses. The surface topography during the HSH process has different characteristics than the PH process and can be used to obtain better friction and lubrication performances.
缸体发动机表面纹理对活塞环组摩擦副系统的功能性能有重大影响。采用白光干涉法（WLI）和体视学分析对珩磨工艺加工的缸体发动机表面微观纹理进行了分析。三维白光干涉仪测量和表面体视学分析方法对于正确解释三维局部表面纹理特征非常重要，并且可以应用于计算摩擦的数学模型中。根据珩磨技术获得的几个阶段（粗珩和精珩以及最后阶段）将样品分为两组：珩磨（PH）样品和螺旋滑动珩磨（HSH）样品来讨论所得结果。结果表明，PH 组的表面具有较高的均方根高度（Sq=1.83μm）和分形维数（Df=2.74±0.01）值，而 HSH 样品的均方根高度（Sq=0.63μm）和分形维数（Df=2.60±0.01）值最低。这些值表明，与 HSH 样品相比，PH 样品的表面（包括形貌）更不规则。
