Spontaneous room temperature extrusion of Pb nano-whiskers from leaded brass surfaces

摘要

We report that lightly abrading the surface of a commercial leaded brass Jesuits in the room temperature spontaneous growth of Pb whiskers and hillocks. The aspect ratios and submicron diameters of the whiskers that form render them easily dispersible in the atmosphere, with potentially serious health effects, especially for people that deal with leaded brass on a daily basis.
