Rehbinder effect
The Rehbinder effect in physics 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,[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]
