| Zusammenfassung: | A non-reactive hard coating of carbon or ceramic is applied to the major components of the spindle motor which are exposed to the atmosphere internal to the hard disc drive. By having such a thin layer of carbon or other ceramic coating, it will protect against outgassing of motor components and create a neutral or non-reactive surface that does not promote corrosion. The coating thickness can be preferably in the order of nanometers to microns depending upon the drive design and the operating conditions. |
