A novel method for preparing aluminum diffusion coating by nanocrystalline plasma electrolysis

A crack-free Al diffusion coating has been developed to improve different properties of commercially pure titanium. It was produced by a method called pulsed bipolar nanocrystalline plasma electrolytic saturation (PBNPES). Morphology and elemental distribution through this layer has been studied with XRD, SEM and EDX. This layer improves the corrosion resistance of bare substrate.
