Texture and Corrosion Behavior of Thin Nickel Sheet Formed by Pulse Plating and Cold Rolling

Abstract

Thin nickel sheets were fabricated by electroforming, and cold rolled to improve their strength. The thin nickel sheets have very fine grains with a {001}huv0i fiber texture. Cold rolling results in evolving a {001}h110i orientation and the formation of a weak {111}huvwi fiber component. Micro-hardness of the nickel sheet on the surface normal to the normal direction (ND) was increased from 247.8 to 354.4 Hv by cold rolling with 87.5% reduction. The corrosion potential and corrosion rate of the nickel sheet in artificial sea water were in the ranges of ¹27 to ¹12 mV SCE and 4.2 © 10 ¹7 1.8 © 10 ¹6 A cm ¹2, respectively. The change in corrosion behavior with cold rolling on the surface normal to ND has little relation to crystallographic texture because of a stable {001} texture during rolling, unlike nickel bulk samples.

Characterization of high phosphorous containing hot rolled weather resistant structural steels

“…Texture and deformation route of the alloys and steels reportedly influence their corrosion behavior [19][20][21]. Certain grain orientations of textured material may be more sensitive to chemical attack.…”
