Abstract
In the paper, experimental and numerical results of the wear of a molybdenum disulfide coated on a titanium alloy disk are reported. The coating is in contact with a sapphire ball. The experiments are conducted for ambient temperatures varying from 20 to 350 \(^\circ \)C. The results indicate that the wear profile becomes increasingly pronounced at the growth of the temperature up to 350 \(^\circ \)C. A numerical model is proposed to describe the results of the experiment. The central assumption is the thermal steady state forming in the interface area. The resulting stress field serves as input for the simulation of wear. A good agreement can be observed between the experimental findings and the FE calculations.
本文报告了钛合金盘上二硫化钼涂层磨损的实验和数值结果。涂层与蓝宝石球接触。实验的环境温度为 20 到 350 摄氏度。结果表明，在温度升高到 350 C 时，磨损轮廓变得越来越明显。我们提出了一个数值模型来描述实验结果。核心假设是在界面区域形成热稳定状态。由此产生的应力场可作为模拟磨损的输入。实验结果与 FE 计算结果之间有很好的一致性。
期刊介绍：
This interdisciplinary journal provides a forum for presenting new ideas in continuum and quasi-continuum modeling of systems with a large number of degrees of freedom and sufficient complexity to require thermodynamic closure. Major emphasis is placed on papers attempting to bridge the gap between discrete and continuum approaches as well as micro- and macro-scales, by means of homogenization, statistical averaging and other mathematical tools aimed at the judicial elimination of small time and length scales. The journal is particularly interested in contributions focusing on a simultaneous description of complex systems at several disparate scales. Papers presenting and explaining new experimental findings are highly encouraged. The journal welcomes numerical studies aimed at understanding the physical nature of the phenomena.
Potential subjects range from boiling and turbulence to plasticity and earthquakes. Studies of fluids and solids with nonlinear and non-local interactions, multiple fields and multi-scale responses, nontrivial dissipative properties and complex dynamics are expected to have a strong presence in the pages of the journal. An incomplete list of featured topics includes: active solids and liquids, nano-scale effects and molecular structure of materials, singularities in fluid and solid mechanics, polymers, elastomers and liquid crystals, rheology, cavitation and fracture, hysteresis and friction, mechanics of solid and liquid phase transformations, composite, porous and granular media, scaling in statics and dynamics, large scale processes and geomechanics, stochastic aspects of mechanics. The journal would also like to attract papers addressing the very foundations of thermodynamics and kinetics of continuum processes. Of special interest are contributions to the emerging areas of biophysics and biomechanics of cells, bones and tissues leading to new continuum and thermodynamical models.
