Role of Surface Roughness in the Interlayer Boundary Formation during Manufacturing of Clad Metal Composites

Abstract:

In the present research work, the role of surface roughness in the interlayer boundary formation during manufacturing of clad metal composites was analyzed. Process of interlayer boundary formation was described through mathematical and computer simulation. The importance of taking into account not only arithmetical mean roughness R_a or ten-point mean roughness R_z, but also R_z/S ratio (where S – mean spacing of adjacent peaks) is shown, because this relation affects the length of actual contact between dissimilar materials. As the result of mathematical and computer simulation, dependence of the length of actual contact between dissimilar materials on R_z/S ratio and semi-angle of the ridge vertex was obtained.
