Experimental Investigation of Different Material Surface Morphology on Formation of Transfer Layer

M. Basavaraju [3] | Maharudra [4]


Abstract: Metal is made both hot and cold in the industrial sector to make technological components. The surface condition of the dies used in these manufacturing processes is one of the many factors that define the surface quality of engineering components. The tribological phenomena at the die and component contact has a significant impact on the surface finish of engineering components. The surface finish of the products is discovered to be controlled by lubrication, die surface morphology, and die surface hardness. The current study employed a pin - on - plate sliding tester to determine how surface morphology, lubrication, and hardness affect the transfer layer's coefficient of friction and transfer, which define the tribological behavior. Three distinct surface modification techniques, including shot blasting, electric discharge machining, and grinding (silicon carbide wheel polishing), were used to alter the morphology of mild steel (EN8) plate surfaces. A three - dimensional optical profilometer was used to measure the surface roughness characteristics that describe the morphology of the steel plates. Using lead, copper, and aluminum (Al6082) pins pushed across steel plates, the role of hardness is investigated. Plate inclination angles of 1, 1.5, 2, and 2.5 degrees were tested in the experiments. During the experiments, the normal load was changed from 1 to 150N. The experiments were carried out in an ambient setting with lubrication. Using a scanning electron microscope, the development of transfer layers on plate and pin surfaces was examined. The co - efficient of friction and the creation of the transfer layer were shown to be dependent on the tougher surface's surface shape when it was lubricated. With an increase in surface roughness, it is discovered that the quantum of transfer layer development on the surfaces increases.
