The Size of the Friction Coefficient Depending on the Size and Course of Normal Load LABAŠOVÁ Eva Department of Applied Mechanics, IPSM, Faculty of Materials Science and Technology, Slovak University of Technology, Paulinska 16, Trnava, Slovak Republic eva.labasova@stuba.sk Keywords: coefficient of fiction, sliding pair, sliding velocity, normal load, bronze bushing Abstract.
To be able to define what mutual interaction of components made of same or different materials, which are in sliding motion to each other, will be like, it is essential to characterize the friction.
Parameter, characterizing resistance of surfaces of couple of bodies from same or different materials in process of friction is called coefficient of friction (m).
The force of friction has the direction of the tangent to the surface of journal (Fig. 1), [4].

Approximately one half of both materials samples were cast in the horizontal direction and the other half in the vertical direction.
It was found that the specific fracture energy of horizontally cast prisms was approximately 4.5 times higher for both materials than that of the vertically cast ones.
