棉纤维股线与303钢线接触摩擦磨损行为分析
Friction Behavior between Cotton Fiber Strand and 303 Steel with Line Contact
摘要
Abstract
Studies have shown that when examining fibers and metals(or other solid materials),the focus is often put on the impact on fibers only,while the friction and wear of metals(or other solid materials)are overlooked due to their perceived"lighter"wear.To investigate the friction and wear behavior of cotton yarn on metal surfaces during cotton textile processing,an independent line contact friction and wear experimental device was constructed.The structure of different strands of cotton yarn was examined with an electron microscopy,and the effects of loading,preload tension,speed and number of cotton yarn strands on the friction and wear performance of metal surfaces were analyzed by a line contact friction and wear test.A 3D surface profiler was used to characterize the change of metal surface morphology with wear time.The amount of wear was predicted based on the Archard wear model.It was noted that the more the number of cotton yarn strands,the smaller the coefficient of friction at the same loading.The effect of preloaded tension on the coefficient of friction under the same number of strands was smaller than that of the loading,and the effect of speed on the coefficient of friction was smaller.The depth of abrasion on the metal surface increased with wear duration,the maximum abrasion depth was 23.158 μm,and the amount of wear increased with the increase of wear volume.As the wear duration increased,the degree of wear on the surface of 303 steel varied,leading to changes in the roughness and friction coefficient of the wear marks.The wear amount increased with the increase of the volume of the wear marks.When the wear duration reached 120 hours,a chain reaction occurred in the nondirect contact area,leading to a continuous expansion of the damaged area.Compared with the metal wear at 24 hours,it becomes severe at 48 hours,with a 71%increase in wear amount.The change in wear amount at 96 hours is relatively small compared to other wear time periods.This is similar to the pattern of severe initial wear,slow stable wear,and intensified severe wear.In the wear stage,the changes in the area and the volume of the abrasion were similar,both of which were positively correlated with the wear time,and when the wear duration reached 120 h,the non-direct contact area produced a chain reaction resulting in an expanding damage area.As the wear time continued to increase,the volume of wear marks increases,and the wear amount increased,which was in line with the universal law.Therefore,cotton yarns cause damage to metal surfaces under continuous friction conditions and the predictions based on the Archard wear model are in better agreement with the experimental results.关键词
