Wear Behaviour of Nanocrystalline Fe88Si12 Alloy in Water Environment

Wear Behaviour of Nanocrystalline Fe88Si12 Alloy in Water Environment

Wear behaviour of nanocrystalline Fe88Si12 alloy has been investigated in water environment compared with the coarse grained counterpart. The friction coefficient of the Fe88Si12 alloy changes slightly with the grain size. The wear resistance is enhanced as the grain size decreases first and then re...
