abstract = "High carbon steels are used in plane pieces and processes of low
forming. Their main characteristic is the high mechanical
resistance and good tenacity. They are mostly used in the
automobile industries, electroelectronics, building sites, and
also as springs, rings, pins, knives etc. This group of steel
possesses a higher percentage of carbon, that facilitates to
obtain pieces with high hardness and high flexibility, but as all
carbon steels, they are very susceptible to severe corrosion. It
is well known that chromium content above 12% in Fe alloys
increases significantly their corrosion resistance. In order to
obtain this improvement, we studied the introduction of chromium
atoms into the matrix of SAE 1070 steel by Plasma Immersion Ion
Implantation and Deposition (PIII\&D) method, in which an RF
magnetron sputtering (MS) is used as the metal plasma source.
Chromium films were deposited by RF magnetron sputtering only and
compared with one formed by PIII\&D at 10kV, 40 {\`{\i}}s, 300
Hz for 60 minutes. Potentiodynamic scans showed that chromium
films formed by PIII\&D leads to a gain in the corrosion
potential and the decrease in the corrosion current density,
promoting bigger corrosion resistance. Furthermore, PIII\&D
chromium films were much more adherent to the samples surface than
MS films. Other characterization tests as nanoindentation, Auger
Electron Spectroscopy, pin-on-disk tribology, scratching test and
surface morphology will be shown in the conference.",
