Hybrid composite films made of an organic polymeric matrix and an inorganic nanosized filler, namely titania prolate nanoparticles, have been prepared and characterized both thermally and mechanically. The filler content has been varied, while still being kept in the regime of unsaturated, homogeneous nanocomposites. On increasing, the filler content there is an abrupt increase in hardness at an intermediate load, while the elastic modulus increases almost linearly. The glass transition temperature is also increased, with a tendency to saturation. The morphological characterization of the films confirms a lack of phase separation, with only a continuous, slight increase in surface roughness, and no major effects on the top film features.

“…With the areal error map, quantitative surface parameters are needed for surface characterization in 3D. Although there is a lack of standard parameters for 3D surface characterization, there are some standards relating to the analysis of 3D areal surface texture, including ISO 25178 and EUR 15178 EN [17]. The 3D surface parameters can be classified into five groups, including Height parameters, Functional parameters, Spatial parameters, Hybrid parameters and Features parameters.…”

Fast tool servo diamond turning is a promising machining method for precision and complex micro-structured surfaces with spatial wavelength above tens of microns. It is crucial to measure and characterize the micro-structured surfaces to sub-micrometer form accuracy. The general purpose measurement instruments are not able to evaluate the true form accuracy between the measured surface and designed surface. Therefore, in this paper an automatic surface characterization method is proposed to evaluate the form accuracy for micro-structured surfaces. The fabricated surfaces can be measured by any high-resolution measurement instruments. After the surface measurement, an iterative closest point (ICP) algorithm is modified to align the measured surfaces to the designed surfaces with the form error evenly distributed over the whole surface. After alignment, the designed surface height corresponding to each measured point is calculated to form the areal error map. 3D surface parameters are chosen and calculated from the error map to characterize the surface form error. Experimental results demonstrate the effectiveness of the proposed surface characterization method.

“…Then roughness parameters related to the height distribution were calculated. The roughness parameters are defined by the standards ISO 25178-2 and EUR 15178N [12,13], as shown in table 1. The reformed parameters S bi * , S ci * and S vi * are defined in previous reported research [19] as modifications to the parameters in the standard, and the algorithms are given in the appendix B.…”

“…To evaluate these surfaces, parameter sets, rather than single parameter for whole profile, were developed based on different functional regions or height stratification [11]. Most methods are derived from the Abbott curve: the core height S k parameter set, volume functional parameter set and the probability material ratio method [12,13]. These surfaces are classified as bi-Gaussian surfaces, because they are combinations of a low rough upper Gaussian surface and a high rough valley Gaussian surface.…”

Characterization of surface topography is very important for understanding and predicting the tribological behavior of engineering parts. Surface texturing has been found beneficial in modifying the tribological properties. However, there still lacks an effective method to describe the topographic features of textured surfaces. In this work, textured surfaces are modeled based on the Abbott curve. Roughness parameters are evaluated to effectively characterize the influences of texturing to functional properties. A parameter set of plateau root-mean-square height S pq , reformed surface bearing index S bi * , reformed core fluid retention index S ci * and reformed valley fluid retention index S vi * is suggested to be used for textured surfaces. S pq reflects the roughness of contact region, while S bi * , S ci * and S vi * give information of change of functional properties in peak, core and valley area, respectively. Using this parameter set, it is possible to reflect the roughness statues of surface before texturing and to quantify the effect of textures on the base surface in peak, core and valley area, and further, to predict their influence on the functional properties, such as contact, oil retention and debris catching capacity.
