类金刚石薄膜的摩擦学性能研究进展
Research Progress on the Tribological Properties of Diamond-like Carbon Films
摘要
Abstract
Diamond-like carbon(DLC)films,known for their outstanding hardness,high elastic modulus,low friction coefficient,and excellent wear resistance,are ideal solid lubricants for achieving engineering superlubricity in aerospace and automotive applications.However,their poor thermal stability and insufficient adhesion strength between the film and the substrate severely hinder their widespread industrial application.Herein,the structural characteristics and typical deposition methods of DLC films are reviewed,and an in-depth analysis of how elemental doping and multilayer structure design modulate the film structure and tribological performance is provided.Moreover,it elucidates how theoretical simulation methods such as molecular dynamics reveal the microscopic regulatory mechanisms of these experimental modification strategies as well as the superlubricity mechanisms of DLC films at the atomic scale.Finally,the current challenges in DLC tribology research and future research directions are discussed.关键词
