lubricants steel abrasion surfaces wear-self-repairing repairing coating additives tribological performances X-ray energy dispersive spectroscopy scanning electronic microscope
To improve the wear-self-repairing performance of the steel material machine parts,a new type of lubricant containing two additives of activated Zn and Sn is prepared.The behavior of wear-self-repairing and tribological performance on steel-steel plane contacting tribo-pair added with this lubricant is studied on a modified MS-800 friction and wearing tester.Surface elemental distribution,repairing coating thickness and its surface appearance are analyzed with an X-ray energy dispersive spectroscopy and scanning electronic microscope.The results indicate that the prepared Zn-Sn composite lubricant has a good obvious lubrication repairing and wear reducing anti-friction performance to steel abrasion surface.The repairing coating can form the thickness of 20 μm on the surface while the machine is running.
