用于轴承和齿轮等机械部件的摩擦学涂层在高度局部化的接触条件下可能会在表面发生失效。在本研究中，有限元分析（FEA）模型被开发来研究在纳米压痕下的碳化钨增强的非晶碳氢化合物涂层的应力分布和变形的柱状微观结构和没有。结果表明，这些摩擦学涂层的微观结构对重载条件下的应力分布和变形有显著影响。Copyright © 2008 by ASME
Tribological coatings for mechanical components such as bearings and gears can experience failure occurring at the surface for highly localized contact conditions. In the present study, a finite element analysis (FEA) model was developed to study the stress distribution and deformation of tungsten carbide reinforced amorphous hydrocarbon coatings with and without columnar microstructures under nanoindentation. Results show that the microstructure of these tribological coatings significantly influences the stress distribution and deformation under heavily loaded conditions.Copyright © 2008 by ASME
