    Oct 27, 2016 · Tribological behaviors of ground 316 substrates, plasma nitrided 316 (PN 316), surface textured 316 (ST 316), and duplex treated 316 (DT 316) in air and under grease lubrication were investigated using a pin on disc rotary tribometer against counterparts of high carbon chromium bearing steel GCr15 and silicon nitride Si 3 N 4 balls. The [plate]Study on Friction and Wear Behavior of Inconel 625 [steel]Friction during the hot extrusion of Inconel 625 superalloy tubes causes severe wear of the mold and plays a decisive role in the quality of the workpieces. In this paper, a ball to disk method was utilized to investigate the tribological behavior of Inconel 625 using two different tribological pairs, i.e., GCr15 and Si 3 N 4 , at room and elevated temperatures.[plate]Tribological performance of poly(sodium 4 [steel]Apr 01, 2012 · During the test, the upper steel ball (GCr15 bearing steel, diameter 10 mm) slides reciprocated at an amplitude of 1 mm against the stationary steel discs (GCr15 bearing steel, Ø 24 mm × 8 mm). All tests were conducted at room temperature of 22°C, frequency of 50 Hz and amplitude of 1
