摘要

分析了涂覆体在弹性变形过程中接触的压痕模型与扁平模型的比较。在广泛的材料（包括软涂层和硬涂层）中研究了涂层厚度和弹性模量比对这两种方法的影响。通过数值拟合建立了过渡参数与有效弹性模量的本构关系。基于GW模型，将涂层粗糙度的接触关系应用于涂层粗糙表面。探讨了涂层厚度、材料性能和基体表面粗糙度对涂层表面变形的影响。比较了两种模型在弹性变形至极限时的等效塑性指数。讨论了产生差异的原因。该研究为涂层粗糙表面的摩擦磨损研究提供了理论基础。

Comparative investigation of the contact coated rough surface coatings using the indentation and flattened methods

A comparison between the indentation and flattened model for the contact of coated asperities during the elastic deformation was analyzed. The influence of the coating thicknesses and elastic moduli ratios on the two methods was studied in a wide range of materials (including soft and hard coatings). The constitutive relationships of the transition parameters and the effective modulus of elasticity were established by numerical fittings. The contact relations of the coated asperity were applied to the coated rough surfaces basing on the GW model. The influence of coating thicknesses, material properties and the surface roughness of substrate on the deformation of the coating surface were explored. The equivalent plasticity index of the two models were compared during the elastic deformation till to the limit. The reasons for the differences are discussed. This study provides a theoretical foundation for the friction and wear of the coated rough surfaces.

期刊介绍： Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide: • a fast means of communication • an exchange of ideas among workers in mechanics • an effective method of bringing new results quickly to the public • an informal vehicle for the discussion • of ideas that may still be in the formative stages The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
