Surfaces Designed for High and Low Friction

2009-2-14  A high friction is desirable in numerous applications such as fixtures, cou-plings and bolted joints. The high friction can be achieved in two ways, ei-ther by choosing a high-friction material combination or by producing a rough surface on the harder member of the friction couple and thus increas-ing the ploughing component of friction.
