Tribological behaviors of natural attapulgite nanofibers as an additive for mineral oil investigated by orthogonal test method

Natural attapulgite nanofibers were added into lubricating oil to improve the tribological behaviors. Orthogonal experiment design was performed to study the effects of load, frequency, duration and concentration on the tribological properties of the additive by SRV reciprocating wear tester. Results indicate that the order that affects the tribological performances of the additive is load, concentration, frequency and duration. A tribolayer...
