FLUID RESISTANCE OF RESIN BONDED SOLID FILM LUBRICANTS

摘要

In order to make recommendations to Design engineers, data con coning the adhesion of resin bonded, solid film lubricants, operating in the environment of various fluids, is necessary; The solid film lubricants tested in this program were Electro film 66C, Electro film 2006, Ever lube 620, and molykote X-106. These films were tested in fluid environments of JP-4 fuel, HIL-L-7808 synthetic base lubricating oil, MIL-L-7870 petroleum base lubricating oil, MIL-H-5606 petroleum base hydraulic fluid, and Dow Corning 710 silicone fluid. The solid film coated test cups were tested on the MacMillan tester, utilizing a, 630-pound normal force on the bearing surface and rotary motion at 66 rpm. None of the bearings tested survived the required 200,000 cycles necessary for passing, regardless of the fluid in which they were tested.
