| Research Abstract |
Fundamental mechanism of the triboelectromagnetic phenomena was analyzed focusing on the triboplasma generation and the guideline to the development of the triboplasma application technology was proposed. It was found that the triboplasma is generated even inside the sliding contact, and the photon emission from the inside of sliding contact under oil lubrication was shown to be caused by the excitation of the dissolved gas molecules. The temperature rise of the triboplasma was successfully measured to give that the triboplasma is non-equilibrium low temperature plasma. The mechanism of photon emission from the sliding surface was analyzed to be caused by the attack of the electrons in the plasma, and the triboplasma generationwas theoretically analyzed to give the potential and the charged particle distributions in the gap. Further, the mechanism of triboplasma generation under oil lubrication was clarified to be due to the electron avalanche process in the cavity formed in the rear gap of the sliding contact with a new model. It was proposed that triboplasma can be controlled by magnetic field application and control of the electric resistivity of tribomaterials.
