Web14 Dec 2015 · Surface roughness is one of the important factors which influence the mechanical properties of the joints. The relationship between the surface roughness and adhesion is very complex. Most of the researchers [ 7 – 9] noticed the importance of surface and its positive influence on the bond strength. Surface roughness can be regarded as the quality of a surface of not being smooth and it is hence linked to human (haptic) perception of the surface texture. From a mathematical perspective it is related to the spatial variability structure of surfaces, and inherently it is a multiscale property. It has different … See more Surface roughness, often shortened to roughness, is a component of surface finish (surface texture).
