摘要: Surface texture of a tool plays an important role as it primarily controls the frictional behavior at tribo interface. In present investigation, pin-on-plate sliding tester was used to identify effect directionality surface grinding marks on coefficient friction and transfer layer formation. 080 M40 steel plates were ground achieve different roughness with unidirectional marks. Super purity aluminium pins slid velocity 2 mm/s against prepared plates. Grinding angle (i.e., between direction marks) varied 0 o 90 in tests. Normal load from 120 N during Experiments conducted under both dry lubricated conditions ambient environment. Scanning electron micrographs contact surfaces study features that included morphology layer. parameters measured using optical profilometer. It observed formation depends harder mating surface. Under conditions, stick-slip phenomena observed, amplitude which plowing component friction. The presence motion could be attributed molecular deformation lubricant confined asperities. variation friction, turn mean slope profile
