The rear axle on my fat bike likes to work itself loose while i ride.

it is this one

cam on one side, thumb nut on the other. The cam isn't opening, it just ends up loosening over a couple hours.
All of the contact faces are smooth. which i think is the problem.
maybe some carbon friction paste? or some type of thin friction washer?

i see orbea used a split washer, but those aren't great with a cam.
 
Is the lever rotating counter-clockwise? If the lever stays closed, and doesn't rotate loose, but the skewer loosens, I would start with user error (sorry), then try a different skewer, then check the dropouts for flex.
