Inorganic Solid Film Lubricants.

Abstract

A GENERAL classification of solid lubricants as well as a discussion of properties, application, and theories has been the subject of numerous investigations (3,5,6,8,9,12). Methods for utilizing solid film lubricants for ball bearing applications (7) have also been investigated. Experimental data on organic resin-bonded solid films indicated that film stability decreases with increase in tem-

Low-friction, high-endurance, ion-beam-deposited PbMoS coatings

“…Also, coatings made with the MoS 2 target had high (10% or more) C content but no structural differences to other IBD Pb-Mo-S coatings. This carbon content is not necessarily detrimental; it has been previously noted that additions of graphite to MoS 2 can improve lubricant performance [1,28]. Despite the scatter, the 17 IBD PbMo-S coatings studied provide clear improvements over even the 29 optimized IBAD MoS 2 coatings in endurance testing.…”

“…Simple mechanical alloying of MoS 2 with graphite [1] is an early example; other additions include compounds such as Sb 2 S 4 [2,3], which improved high temperature performance. Early sputter deposition techniques employed small amounts of metal additives (e.g.…”

Recent Progress on Irradiation-Induced Defect Engineering of Two-Dimensional 2H-MoS2 Few Layers

“…There is little literature on γ-irradiated bulks. It was reported that MoS 2 powders were resistant to a γ-ray irradiation with a dose of 5 × 10 9 R (1.29 × 10 6 C/kg) [105].…”

Environmental Effects on the Tribology and Microstructure of MoS2–Sb2O3–C Films

“…Operation under ambient, humid conditions has been found to lead to high friction, wear, and premature failure [8]. In the past, materials such as gold [9,10], titanium [11], lead [12], carbon [13][14][15] tungsten diselenide (WSe 2 ) [16], and antimony trioxide (Sb 2 O 3 ) [17,18] have been evaluated as additives in an effort to address this problem.…”
