摘要:

构建一个表面,是摩擦系统的功能(确定性表面)的一个组成部分是一个有趣的目标。这种表面的灵感来自于研究自然系统和推导设计规则。主要的吸引力是,自然系统,而功能复杂,一般来说,优化的形状和性能。人们进一步认为,自然系统的功能复杂性是自然物种不断变形以适应运行环境的原因。其中一种生物物种是球蟒。这是因为这样的物种不断地在各种表面上滑动,其中许多表面被认为是摩擦学上敌对的,而不会受到太大的损害。该物种在适应环境方面的成功很大程度上归功于表面设计特征。在这方面,研究这些特征以及它们如何有助于控制摩擦和磨损是非常有吸引力的。本文件是朝这个方向迈出的一步。在这项工作中,我们应用多尺度表面表征方法来研究Python Regius的表面设计功能。重点是那些通常用于评估高质量润滑表面性能的特征。为此,通过SEM和白光干涉法(WLI)研究了地形特征。我们探测多尺度上的表面粗糙度,并作为体内位置的函数。此外,我们还将这些特征与人类皮肤的特征进行了比较。

英文摘要:

Constructing a surface that is an integral part of the function of tribosystems (deterministic surface) is an intriguing goal. Inspirations for such surfaces come from studying natural systems and deducing design rules. The major attraction is that natural systems, while functionally complex, are, in general, of optimized shape and performance. It is further believed that functional complexity of natural systems is what affords natural species to morph continuously to adapt with the operating environment. One bio-species that is of interest is the Ball Python. This is because such a species continuously slides against various surfaces, many of which are deemed tribologically hostile, without sustaining much damage. Much of the success of that species in adapting to its environment is attributed to surface design features. In that respect, studying these features and how do they contribute to the control of friction and wear is very attractive. This paper is a step in this direction. In this work we apply a multi scale surface characterization approach to study surface design features of the Python Regius. The focus is on those features that are typically used to assess the performance of high quality lubricating surfaces. To this end, topographical features are studied by SEM and through White Light Interferrometery (WLI). We probe the roughness of the surface on multi scale and as a function of location within the body. In addition we draw a comparison of these features to those of human skin.
