| Popis: |
In this study, CrMn, CoCrPt-C multilayers and carbon overcoat were sequentially deposited on the NiAl coated glass substrate as underlayer, granular media layer, and protect layer by DC sputtering. Samples with various interlayer carbon concentration and top-layer carbon were tested for corrosion resistance in the 0.5 N HCl saturated vapor environment. The results show that surface concentration of cobalt and nickel varies with the carbon content in the magnetic layer. An nonannealed top-layer carbon and low temperature annealed interlayer carbon can provide grain-sized or nanoscale protection to the CoCrPt magnetic media. Carbon concentration within/above the top of CoCrPt-C granular thin film plays an important roles in the suppression of corrosion. |
