项目摘要

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.

分析了摩擦电磁现象产生的基本机理，重点讨论了摩擦等离子体的产生，并对摩擦等离子体应用技术的发展提出了指导意见。结果发现，摩擦等离子体的产生，甚至内部的滑动接触，从内部的油润滑下的滑动接触的光子发射被证明是由溶解的气体分子的激发。成功地测量了摩擦等离子体的温升，证明了摩擦等离子体是一种非平衡低温等离子体。从理论上分析了摩擦等离子体的产生机理，给出了差距中的电势和带电粒子的分布。进一步，提出了油润滑条件下摩擦等离子体产生的新模型，阐明了摩擦等离子体产生的机理是由于滑动接触后间隙中形成的空穴中的电子雪崩过程。提出了通过施加磁场和控制摩擦材料的电阻率来控制摩擦等离子体的观点。
