چکیده انگلیسی
Dry film lubricant (DFL) coatings are widely used to reduce coefficients of friction and damage in highly loaded contacts. This work investigates the behaviour of a commercially available MoS2-based DFL in a cylinder-on-flat contact geometry with a fretting amplitude of 300 μm with a range of cylinder radii and DFL thicknesses. Three stages in the lifetime of the system were identified. In the first stage, the DFL wore with a volumetric rate that was proportional to the number of cycles (under a given load), until the thickness of the DFL was reached; in the second stage, a thin low friction surface layer existed, with its durability being proportional to the contact pressure; in the third stage, metal-metal contact resulted in short-term instabilities in the coefficient of friction and the DFL system was said to have failed.
