In order to clarify the degradation mechanisms of the PFPE fluid under a head/disk sliding contact, decomposition reactions of z-dol fluids were investigated under triboplasma generation and in the atmospheres of oxygen, nitrogen and air in gas-discharge-plasma. The results showed that the PFPF degradation proceeds through intermolecular reactions with ambient air molecules by the tribomicroplasma.
