Effect of Addition of Sodium Ascorbate on the Property of the Plated Fe-Ni-W Alloy-Film

Abstract

The effect of adding sodium ascorbate into the plating bath used for Fe-Ni-W alloy has been investigated for its wear properties. Fe-Ni-W alloy film containing up to 31.1 at% tungsten can be prepared with the moderate addition of sodium ascorbate into the bath. Fe-Ni-W alloy film prepared under such conditions tends to include certain contents of hydrogen, which induce film embrittlement. However, results also suggest that moderate heat treatment of the embrittled film can improve its hardness and wear properties.
