The behaviour of permalloy in NH4F/HF solutions
Source abstract
Abstract
Abstract The oxidative behaviour of Ni80Fe20 (Permalloy) in an NH4F/HF solution was investigated. The influence of O2 concentration and the effects of short-circuiting Permalloy with a large area Pt or Alsimag electrode on the corrosion were studied. Current–voltage curves were measured to unravel the mechanism of corrosion. The corrosion started with the preferential dissolution of Fe. Possible corrosion prevention was examined by influencing the anodic and cathodic partial currents of the corrosion process.
