Wear Failure Behavior of Steel Surface with Palygorskite Powders as Lubricant Additives

Abstract:

Wear failure behavior of steel surface with palygorskite powders (Palys) as lubricant additives was investigated in this paper. Different content of Palys was added in different lubricating oils. The wear failure behavior of the steelsteel contact surfaces was studied by using an optimal SRV oscillating friction/wear tester. The elemental component and morphology on worn surface were analyzed by SEM and EDS. From the results of the friction/wear tests and analysis of the worn surfaces, we can see that specimens with Palys as lubricant additives exhibit excellent wear reducing properties and introduce a smooth and compact oxide layer on the worn surface. This may be attributed to the layer-chain fibrous crystal structure of palygorskite and the complex physicochemical nature in friction process.
