ABSTRACT:
Plastic molded articles having low friction and excellent wear resistance are produced by treating the surface of the plastic article with an aqueous solution of an inorganic fluoride such as hydrogen fluoride. Plastic articles which can be made in accordance with the invention include plastic brake pistons, bearings, motors and drives, commutators, slip ring alternators for DC drive motors, thrust washers, spacers and reactors, clutch plates, electrical switching equipment with sliding parts, gears, pulleys for belt drives, such as cog belt pulleys, V-belt pulleys and poly V-belt pulleys, gas meter discs, and the like. In addition to the treatment step, the plastic articles are neutralized, washed and dried.
