The microhardness of zinc monocrystal electrodes immersed in an aqueous electrolyte is shown to be sensitive to the applied potential provided that pyramidal slip about the hardness impression produces surface steps. Unlike some crystalline nonmetals and glasses in which environment-induced changes in the space charge layer are considered to be responsible for Rebinder effects, the above behavior in metals cannot be so ascribed. Indeed, it is suggested that variation in the energy required to form a surface slip step with electrode potential accounts satisfactorily for the present observations. Author
