At the same time, the contact stress changing with the flank angle and friction coefficient was calculated......
coefficient of the composite coating against steel under dry friction test is 0.11, which is 17% lower than that obtained by traditional hardcoat anodizing. 关键词:hardcoat anodizing; aluminum alloys; c omposite coating; PTFE particles; friction coefficient; [全文内容正在添加中] ......
at different brake speeds. It shows that the coefficient of friction and wear volume are greatly influenced by brake speed. When the brake speed is 4000 r/min, which is a bit higher, the material still has a higher coefficient of friction with 0.47. When the brake speed is over 4000r/min, the coefficient of friction decreased rapidly. When the brake speed is 3000r/min, the material''s wear is in its......

process. The results show that the friction coefficient mainly experiences two steady stages. The first steady stage corresponds to the Coulomb friction with material abrasion. The second steady stage corresponds to the stick friction with fully plastic flow. Moreover, the increasing rates of axial displacement, temperature and friction coefficient are obviously enhanced with the increase......

The friction coefficient was measured using a ball-on-disk tribotester.The tests... coefficient. With increasing the applied load and sliding velocity,the friction coefficient of the oil-infiltrated film decreased. It indicates that the oil-infiltrated AAO film produced a new way to modify......
, and the average sliding friction coefficient is between 0.55 and 0.73. The friction coefficients of the interfaces are large, and the friction performance are unstable. It is not suitable for stone structure isolation joint. By smearing the molybdenum disulfide grease in the double-layer steel plate interface, the friction coefficient of the interfaces can be efficiently decreased......
