Surface Charge-Dependent Mechanical Behavior of Non-Metals.
Abstract
When an inorganic nonmetallic solid is immersed in a non-corrosion, surface-active liquid environment, the mobility of near-surface dislocations and/or microhardness is markedly influenced by the surface charge developed on the solid. Specifically, it appears that such solids are hardest at their iso-electric points (as determined from zeta-potential measurements). This paper presents some examples of such behavior, considers possible mechanisms, and discusses how such chemomechanical effects can be employed to control the machining and frictional behavior of ceramics and glasses.
