• Description:
  Surface alloys were fabricated by implantation of 25 key nickel ions into polycrystalline iron to doses ranging from 8.5 X 1015 to 3.4 X 1016 ions/cm2. The aqueous corrosion characteristics were studied under conditions of anodic polarization at 30 deg c in a helium- deaerated sodium borate buffered boric acid solution (ph 8.5) Containing 2,400 ppm chloride ion. The pitting- and general- corrosion characteristics are comparable with nominally equivalent bulk commercial alloys and are superior to those of pure iron. A high-strength maraging steel was shown to exhibit an increase in pitting-corrosion resistance due to the implantation of chromium ions. [Description provided by NIOSH]
