iTSSe TSS A D V A N C E D M A T E R I A L S & P R O C E S S E S | A P R I L 2 0 2 0 4 7 iTSSe TSS behavior could be detrimental to the overall performance of bearing or actuator components. Figures 4a and 4b show the wear scar on the M50 pin tip and on the Triboglide coated Inconel discs. The wear scar on the Triboglide coating, CrC-NiCr + 5% (CaF 2 +BaF 2 ), is minimal and the amount of transferred film on the pin tip is nominal, Fig. 5 — High temperature pin-on-disc testing of Triboglide with silver showing (a) ball wear and (b) wear track on disc. (a) (b) FEATURE 13 indicating an excellent friction coefficient with low noise and minimum galling. The Triboglide coating with added silver shows increased galling on the pin tip as seen in Figs. 5a and 5b, and the wear track on the coated disc is wider, indicating lower wear resistance.
