摘要： 为了有效估计由于粗糙度因素造成纳米压痕测试结果的偏差,对纯铝的纳米压痕进行了有限元仿真研究。利用二维轮廓模型,采用模型轮廓最大高度Ry作为评定样品表面粗糙度的参数,并引入轮廓的波峰与波谷之间的水平距离D和波谷的中垂线与相邻凸面切线之间的夹角θ。仿真发现:相比光滑表面,在不同的接触零点,测试结果存在差异:接触零点为粗糙表面波峰时,最大载荷测试结果偏小;接触零点为粗糙表面波谷时,最大载荷测试结果偏大;压头压向波谷,压头棱边与凸起接触为接触零点时,测试结果引起的偏差相对较小。

Abstract: To effectively estimate the test deviation of nano-indentation due to surface roughness, a finite element simulation of nano-indentation is carried on pure aluminium. A two dimension model is adopted and the maximum height Ry of the model contour is regarded as the assessment of the sample surface roughness parameters. Parameter D represents the horizontal distance between the peaks and valleys of the contour. The angle θ between the valley's midperpendicular and the tangent of adjacent convex is introduced. Compared with the smooth surface, for different initial contact, simulation results show obvious diversity: for initial contact at the peak of the rough surface, the maximum load is smaller; for initial contact at the valley of the rough surface, the maximum load is bigger; for initial contact at the edge of indenter and the bulge of the contour, the result is relatively close to the smooth one.

Key words: nano-indentation, surface roughness, initial contact, finite element method(FEM)
