Rehbinder effect

In physics, the Rehbinder effect is the reduction in the hardness and ductility of a material, particularly metals, by a surfactant film.[1] The effect is named for Soviet scientist Piotr Aleksandrovich Rehbinder [ru],[2][3] who discovered the effect in 1928.[4]

A proposed explanation for this effect is the disruption of surface oxide films, and the reduction of surface energy by surfactants.[1][5]

The effect is of particular importance in machining, as lubricants reduce cutting forces.[5][6]
