Friction and Wear Properties of Sintered Cu Alloy Impregnated with Thermo-Reversible Gel-Lubricant
The friction and wear properties of a sintered porous Cu alloy impregnated with either Thermo-Reversible Gel-Lubricant (TR Gel-Lube) or base fluid (PAO) were investigated. Friction tests were conducted under a wide range of normal loads (0.98 N, 9.8 N, and 19.6 N) and sliding velocities (0.2 m/s, 0....
