摘要: Abstract The effect of grain refinement on the corrosion resistance passive film formed 2099 Al–Li alloy was investigated. microscopic structures cold rolled aluminum were characterized by Transmittance Electron Microscopy and surface activity analysed electron work function. studied electrochemical techniques Raman spectra. It found that nano/ultrafine grained with refined precipitation phases obtained several plastic deformation process. improved phases. after attributed to decreased promoted forming thicker acceptor concentration in film.
