高温加熱された摩擦場におけるDC電場の影響

抄録

It has been reported that the friction coefficient of DLC changes when an electric field is applied while the DLC is heated by laser. It has also been reported that the amount of smear generation in head smear generation in heat-assisted magnetic recording also changes depending on the applied electric field. These suggest that the amount of decomposition products of DLC can be controlled by applying an electric field to the friction interface. On the other hand, it has been reported that an amorphous carbon layer is formed when an alkyl diphenyl ether (ADE) lubricant is rubbed. This tribo-film is presumably due to the decomposition of ADE by tribo-chemical reactions. Therefore, we conducted friction tests with pentaphenyl ether (5P4E), 5P4E lubricant, while applying an electric field, and analyzed the tribo-film formed by Raman analysis. The results showed that the formation of an amorphous carbon tribo-film was easily achieved by the application of an electric field.
