Abstract
The purpose of this study is to investigate the friction and wear behavior of novel electrostatic micro-solid lubricant (EMSL) bonded molybdenum disulfide (MoS2) coatings on cemented carbide tools under dry slide condition. Pin-on-disc tribological tests between titanium alloy Ti–6Al–4 V and uncoated/coated cemented tungsten carbide–cobalt alloy (WC–Co) were carried out over a range of experimental domain of sliding speeds and normal loads. Specimen wear rate and friction coefficient were investigated. Tribological tests demonstrate that EMSL bonded MoS2 coatings provide excellent anti-friction and reasonable wear performances. The mechanism of enhanced friction and wear behavior with the MoS2 coatings is discussed. This study explores the feasibility of using EMSL coatings onto tribological components and opens a new way to implement bonded MoS2 solid lubricant coatings as a new candidate for tribological operations.
