Effect of surface roughness in the determination of the mechanical properties of material using nanoindentation test

et al. 2013

A quantitative model is proposed for the estimation of macro-hardness using nanoindentation tests. It decreases the effect of errors related to the non-reproducibility of the nanoindentation test on calculations of macro-hardness by taking into account the indentation size effect and the surface roughness. The most innovative feature of this model is the simultaneous statistical treatment of all the nanoindentation loading curves. The curve treatment mainly corrects errors in the zero depth determination by correlating their positions through the use of a relative reference. First, the experimental loading curves are described using the Bernhardt law. The fitted curves are then shifted, in order to simultaneously reduce the gaps between them that result from the scatter in the experimental curves. A set of shift depths, Δhc , is therefore identified. The proposed approach is applied to a large set of TiAl6V4 titanium-based samples with different roughness levels, polished by eleven silicon carbide sandpapers from grit paper 80 to 4,000. The result reveals that the scatter degree of the indentation curves is higher when the surface is rougher. The standard deviation of the shift Δhc is linearly connected to the standard deviation of the surface roughness, if the roughness is high-pass filtered in the scale of the indenter (15 µm). Using the proposed method, the estimated macro-hardness for eleven studied TiAl6V4 samples is in the range of 3.5-4.1 GPa, with the smallest deviation around 0.01 GPa, which is more accurate than the one given by the Nanoindentation MTS™ system, which uses an average value (around 4.3 ± 0.5 GPa). Moreover, the calculated Young's modulus of the material is around 136 ± 20 GPa, which is similar to the modulus in literature.

“…This component carries information on low-frequency disturbance of the surface in the radial direction of the object [3,7]. Together with wear of elements in the object's turning system, perpendicular displacement of the tool with respect to the object leads to such a character of changes whose values increase with an increase of the wear in exploitation [8]. In reality, such changes occur in a wider and lower band than the tool feed frequency ν f as an irregularity wave group and can be recognized in the spectrum.…”

“…Changes in displacement of the tool in the direction perpendicular to the surface "z" lead to irregular traces of its mapping in the profile and are caused by inaccuracies of the feed system and disturbances in realization of tool feed movements [8,13]. They modulate in frequency the displacement of indentations along the length of the profile and indirectly, to a lesser degree, the heights of irregularities in the form of amplitude modulation, as presented in Fig.…”

“…Contemporary decompositions of surface irregularities by wavelet methods in [4][5][6] do not provide practical technological and useful interpretations. Analyses of filtered irregularities are incomplete in diagnosing their origin [4,7], also the use of standard roughness or waviness parameters does not lead to an analysis of the cause of irregularities [1,8,9]. Analyzing the irregularities with amplitude-frequency functions, the influence of the machine tool upon the object's surface can be grasped to a fuller degree [10][11][12].…”

The paper describes the influence of the machining operation on a surface, which disturbs the projection of the tool profile in the form of its relative movements with respect to the object. The elements of the machine tool undergo constant wear during the machining process, it is therefore important to recognize the effects of their influence on the surface's irregularities. Amplitude-frequency analysis of lateral profiles has been used to evaluate and changes of turned lateral profiles. The results of simulation of radial and axial effects of the machine tool on surface and their spectral components were analyzed. Surfaces obtained in similar machining conditions on lathes operated in various time periods were analyzed spectrally. From the analysis of surface irregularity changes caused by disturbances in movements of the tool against the object, testifying the wear of main machine elements during its operation, the modulated, amplitude-frequency character of changes in surface irregularities of workpiece can be noticed.

“…In [9] the decomposition of surface components by means of wavelet filtration of irregularities. Roughness viewed through various length scales is treated in [10], while publication [11] characterizes waviness lengths by robust filtering. Publications [9−12] apply new methods of component filtration, but they are not related to standard formulations and are not linked by length of frequency with surface profile components.…”

The paper presents a spectral formulation of surface profile irregularity in a wideband frequency range for roughness, waviness and shape components along the measured length. A unique distribution of roughness and waviness components is proposed, according to the nature of their origination in the course of machining with tools of defined cutting edge, as distinct from standard filtration in measurements of surface irregularities. Differences resulting from both formulations are outlined as well as the method of determining the frequency of component separation for surface roughness and waviness.
