Metal is cold-and hot-formed to make technical parts in the industrial sector. The condition of the dies used in these manufacturing procedures is one of the factors that establish the surface quality of engineering components. Tribological activities at the die-component contact have a significant impact on the surface finish of engineering components. The surface finish of the products is affected by lubrication, the form of the die, and the hardness of the die surface. This study used a pin-on-plate sliding tester to determine how surface shape, lubrication, and hardness impact the tribological behavior-defining coefficient of friction and transfer layer transfer. The morphology of mild steel (EN8) plate surfaces was altered using three separate surface modification techniques: shot blasting, electric discharge machining, and grinding (silicon carbide wheel polishing). The surface roughness parameters that characterize the morphology of the steel plates were measured using a three-dimensional optical profilometer. We probe the function of hardness by pushing lead, copper, and aluminum (Al6082) pins over steel plates. The studies were conducted using plate inclination angles of 1, 1.5, 2, and 2.5 degrees. Throughout the trials, the standard load was varied between 1 and 150N. The trials were conducted in a lubricated, ambient environment. Surfaces of plates and pins were studied for the formation of transfer layers using a scanning electron microscope. It was shown that the contour of the lubricated harder surface influenced both the friction coefficient and the formation of the transfer layer. The formation of transfer layers on surfaces is seen to grow as the surface roughness rises.
