主 题：friction microstructure steel
摘 要：The anti-friction function of superwetting surfaces with superhydrophobicity has been ***,the influence regularity of wettability to tribological performance,and the underlying mechanism are still ***,two kinds of microstructured surfaces with different wettability are fabricated on the substrate of steel by controlling surface chemical *** water contact angles on these surfaces range from 0°to 151°.The ball-plate tribological tests are performed under water *** results show that the tribological performance is closely related to surface *** friction coefficient increases with the increase of contact angles when the surfaces are hydrophilic rather than *** contrast,the friction coefficient on the hydrophobic surfaces decreases with the increase of contact ***,the best anti-friction capability is obtained on the superhydrophobic surfaces,and the anti-friction mechanism is *** lowest friction coefficient was 0.12 under the load of 10 *** work provides strong evidence of an association between tribological property and wettability,which may inspire the fabrication and application of special wetting surfaces in friction control.
