不同摩擦偶件对单晶硅摩擦磨损行为影响的对比研究
Comparative Study on Effects of Different Counterparts on Friction and Wear Behavior of Single Crystal Silicon
摘要
Abstract
Friction and wear behaviors of single crystal silicon sliding against different counterparts (Al2O3 and agate) were comparatively studied. Results show that friction coefificient between single crystal silicon and Al2O3 decreases with the increasing of sliding velocity, and it is the same as that between single crystal silicon and agate. Wear volume losses of single crystal silicon sliding against different counterparts all decrease with the increasing of sliding velocity. Under the same experimental conditions, single crystal silicon coupled with Al2O3 displays greater wear volume loss than silicon slid against agate. Regardless of whether the single crystal silicon is sliding against Al2O3 or agate, it has the same wear mechanism. In other words, the worn surfaces of the silicon are characterized by a large number of micro-fractures and plastic deformation when sliding at low speed, while those of the silicon show some kind of polishing effect when sliding occurs at high speed; that is to say, there exists a “velocity effect”. However, worn surfaces of the silicon sliding against agate are smoother than those of the silicon sliding against Al2O3. And these are related to the physical and mechanical properties of single crystal silicon, Al2O3 and agate, especially the hardness of the materials.关键词
