Abstract

Tin surfaces which are corrosion resistant, electrically conductive, and attractively finished are produced by anodic oxidation followed by oil sealing. Addition of an anionic fluorocarbon surfactant -- preferably FC98* -- to the anodizing bath improves the uniformity, texture and oil receptivity of the anodized deposits. This particular surfactant has long term stability at bath operating temperatures (e.g. 194 degrees F). A concentration of 0.8 gms surfactant additive per gallon of anodizing bath fluid is used. * Product of Minnesota Mining & Manufacturing Company.
