Corrosion behavior of nanocrystalline (Ni70Mo30)90B10 alloys in 0.8 M KOH solution
Source abstract
Abstract
Abstract Nanocrystalline materials are claimed to exhibit improved properties as a result of their novel microstructure. The corrosion behavior of nanocrystalline (Ni70Mo30)90B10 alloys prepared by crystallization from the amorphous state was studied and compared with that of their amorphous and coarse-grained counterparts. Special emphasis was given to the relationship between microstructure and corrosion resistance. It was concluded that nanocrystalline (Ni70Mo30)90B10 alloys are less sensitive to corrosion in alkaline solutions than the coarse-grained material. This behavior was related to their small grain size and homogeneous single phase microstructure. They provide a uniform substrate where it is easy to form a passive film, consisting essentially of Ni(OH)2 for the alloy studied.
